실험 절차

5 g. N-[4-(1-Cyano-1-methylethyl)-phenyl]-4-methoxybenzamide (Example 27) are hydrogenated at 90° C. and 120 bar hydrogen pressure in 40 ml. ethanol in the presence of 40 ml. liquid ammonia and 2 g. Raney nickel. The reaction mixture is filtered and the filtrate evaporated to dryness in a vacuum. After column chromatographic purification (400 ml. silica gel 60; dichloromethane/methanolic ammonia 30:1 v/v), there are obtained 2.6 g. of colourless crystals which are heated in 100 ml. 1M hydrochloric acid. After cooling, there are obtained 2.3 g. (40% of theory) of the title compound as hydrochloride in the form of colourless leaflets; m.p. 273°-276° C.
