Reaction Conditions

Reaction Steps

Into 1200 ml of methyl acetate 204 g (5.6 mol) of hydrogen chloride gas is introduced at 15-25° C., and to the solution are added 221.4 g (0.8 mol) of the [2-(2-thienyl)ethylamino](2-chorophenyl)acetonitrile, prepared as described in Example 1., and 48 ml (1.2 mol) of methanol. The mixture is stirred at 20-25° C. for 6 hours. In the course of the reaction first the hydrochloride of the starting “nitrile”, then gradually the hydrochloride of the resulting “acid amide” precipitates, in the form of white crystals. The crystals are collected by filtration, washed with methyl acetate and dried. Weight: 249 g (94%) mp.: 231-232° C.
