Field of the Invention This application is a divisional of Australian patent application number 2002363108 the entire disclosure of which is incorporated herein by reference.
The present invention relates to a novel 4-imidazolin-2-one compound which has an excellent p38MAP kinase inhibitory action and is useful for a medicament.
2. Background Art Mitogen-activated protein (MAP) kinase is a member of serine-threonine kinases which transfers a y-phosphate group of adenosine triphosphate (ATP) to a hydroxy of specific serine or threonine which constitutes a protein, and is involved in various cellular responses against extracellular signals. p38 MAP kinase is an about 38 kDa protein and cloned as a homologue of MAP kinases.
p38MAP kinase is activated by inflammatory cytokines such as tumor necrosis factor a (TNF-a) and interleukin 1 and by stimulation caused by stress such as ultraviolet irradiation. p38 MAP kinase recognizes various transcription factors and protein kinases as a substrate. It has been clearly shown that, being activated by p38 MAP kinase, these transcription factors and protein kinases become involved in promoting transcription, post-transcriptional regulation stabilizing mnRNA and promoting protein translation) or stabilizing proteins, etc. of various proteins including inflammatory cytokines, which are involved in inflammatory reactions. From these findings, it is thought that p38 MAP kinase is critically involved in the various inflammatory reactions by regulating the production and the signal transduction of inflammatory cytokines, and an inhibitor of p38 MAP kinase can highly expected to serve as a therapeutic agent for various diseases including inflammatory diseases.
As the inhibitors for p38 MAP kinase, there have been disclosed imidazole derivatives in PCT Japanese Provisional Y:Mao.NI NO DELETE MR2002363108.doc Patent Publication No.2000-503304, 1,3-thiazole derivatives in Japanese Provisional Patent Publication No. 2001-114690, 1,3-thiazole derivatives and 1,3-oxazole derivatives in Japanese Provisional Patent Publication No. 2001-114779, imidazole derivatives, pyrrole derivatives, furan derivatives, 3-pyrazolin-5-one derivatives, pyrazole derivatives and thiophene derivative, etc. in Expert Opinion on Therapeutic Patents (2000) 10(1) :25-37, respectively.
However, there has been no description on 4-imidazolin-2-one derivatives in any of these.
An object of the present invention is to provide a novel compound having an excellent p38 MAP kinase inhibitory action and is useful as a pharmaceutical.

In 440 ml of THF was suspended 22 g of 2-chloroisonicotinic acid, and under nitrogen flow, the mixture was cooled to or lower., 245 ml of methyl lithium (1.14 M solution in diethyl ether) was added dropwise to the mixture. After stirring at the same temperature for an hour, a temperature of the mixture was raised to 0 C over an hour, and stirred at the same temperature for further an hour. To the reaction mixture was added:500, ml of water, and the reaction mixture was extracted with ethyl acetate, washed.with brine and dried over magnesium sulfate. Activated charcoal was added to the mixture, and after filtration, the filtrate was concentrated under reduced pressure to give 19.5 g of 4-acetyl-2-chloropyridine as colorless crystals. Melting point: 36 0
C.
In 550 ml of ethanol were suspended 55.1 g of the compound obtained in 49.2 g of hydroxylamine hydrochloride and 58.1 g of sodium acetate, and the mixture was refluxed under heating for an hour. After cooling the mixture to room temperature by allowing to stand, ethanol was distilled away under reduced pressure and precipitated crystals were collected by filtration and washed with water. The crystals were. air-dried at 60 0
C
overnight to give 55 g of 1-(2-chloropyridin-4-yl)ethanone oxime as colorless crystals. Melting point: 143 0
C.
In methylene chloride were suspended 105 g of the compound obtained in and 123 g of tosyl chloride, and under ice-cooling, 94 ml of triethylamine was added dropwise to the mixture, and the mixture was raised to room temperature and stirred for 4 hours. To the reaction mixture was added 500 ml of water, and the mixture was extracted with methylene chloride, washed with brine and dried over magnesium sulfate. After 145 filtration, the mixture was concentrated under reduced pressure, and the resulting crystals were collected by filtration and washed with isopropyl ether to give 192 g of 1-(2-chloropyridin-4-yl)ethanone oxime tosylate as colorless crystals.. Melting point: 153 0
C.
Under nitrogen flow, 3.11 g of sodium metal was added to 220 ml of anhydrous ethanol at room temperature, and the mixture was dissolved under stirring. The solution was ice-cooled, and g of the compound obtained in was added thereto, then the mixture was stirred at room temperature for an hour. To the mixture was added 220 ml of anhydrous ether, and insoluble matters were removed. To the filtrate was added 62 ml of 4N hydrochloric acid/dioxane solution under ice-cooling and the mixture was stirred for 15 minutes. After the reaction mixture was concentrated under reduced pressure, the residue was dissolved in water and the solution was made alkaline by addition of potassium carbonate. This mixture was extracted with ethyl acetate several times, and the combined extracts were washed with brine and dried over magnesium sulfate. After concentration under reduced pressure, 100 ml of hexane was added to the residue and red insoluble matters were removed by filtration. The filtrate was concentrated under reduced pressure, hexane was again added to the concentrate and insoluble matters were removed by filtration through Celite.
