Reaction Steps
78 g of 1-(4-benzyloxyphenyl)-2-chloroethanone and 63 g of hexamine are dissolved in 2.2 liters of chloroform, and the mixture is stirred at room temperature overnight. The mixture is condensed to a volume of 1.1 liters, and refluxed for 3 hours. After cooling, the precipitated crystals are collected by filtration, washed and then dried. The colorless crystals thus obtained are added to a mixture of 750 ml of ethanol and 120 ml of conc. hydrochloric acid, and the mixture is refluxed for 50 minutes. After cooling, the precipitated crystals are collected by filtration, washed and then dried. 55.6 g of 2-amino-1-(4-benzyloxyphenyl)ethanone hydrochloride are obtained as colorless crystals.
