    The method for the preparation of 2-- (aminomethyl) -Y hydrochloride, M-diethyl-1-phenylic lopropane (Z) (a medicinal preparation of midalcyrane) which can be used in the chemical-chemical industry.
    The purpose of the invention is to increase the yield of the target product.
    Example 1.1 Phenylbtalimido 2-me; tpcc 1-cyclopropanecarboxylic acid (Z).
    A suspension of 52.56 g (0.3 mol) of 1- (b of nyl-2-oxo-3-oxabicyclo (3: 1: 3) hexane and 61 g (0.33 mol) of potassium ltalimide in 270 ml of dimethyl termamide is kept under stirring at 150 for 12 hours
    The pacTBOD obtained after cooling to room temperature is poured into 1000 ml of water. After extraction with ethyl acetate, the aqueous phase is acidified with acetic acid, then cooled with ice. The acid that crystallizes is filtered off, washed with water and recrystallized from ethnol to give 62.6 g of a highly purified compound (yield 65%).

    16.2 g (0.05 mol) of 1-phenylphthalimido 2 methylcyclopropane carboxylic acid are added at ambient temperature. Get the solution after 2 h at room temperature. Oxalyl chloride can be used at this stage, the process is carried out at a boiling point temperature.
    The solution is then boiled for 2 hours. After removing the excess thionyl chloride, the crude acid chloride in solution in 50 ml of methyl chloride is added dropwise to a solution of 1053 ml (0.1 mol) of diethylamine in 150 ml of chlorine.
