Versuchsvorschrift

Into 20 ml of dry ethanol containing 3.76 g of oa p-(1-trifluoromethyl-heptyloxy)-benzonitrile, about 1 g of dry hydrogen chloride was introduced under stirring at a temperature below 10° C. After stirring at room temperature for 3 days, solvent was distilled off to obtain any oily product. To this, were added slowly 20 ml of dry ethanol containing about 2 g of ammonia under cooling with ice, followed by stirring at room temperature for 3 days. Ethanol and ammonia were removed to obtain 3.40 g of oily oa p-(1-trifluoromethyl-heptyloxy)-benzamidine hydrochloride. This oily hydrochloride was solidified by trituration in hexane to use the following reaction.
