Procedure

On to a mixture of 127.2 g. (0.49 mole) of the acid obtained according to (b) and 800 ml. ethanol is passed, while stirring, gaseous hydrogen chloride and the reaction mixture is heated to reflux temperature for 2 hours, whereafter it is then strongly cooled. The precipitated crystals are filtered off with suction, washed with cold ethanol and dried over anhydrous calcium chloride. Yield 137.1 g. (97% of theory) of hydrochloride; m.p. 162°-165° C.
