実験手順
4.5 g. (0.015 mol) 4-(1,1-Dimethylethyl)-N-(4-nitrophenyl)-benzamide (Example 15 ) are hydrogenated at normal pressure and ambient temperature in the presence of 0.5 g. 10% palladium on charcoal. After 30 minutes, the reaction mixture is filtered and the filtrate is evaporated in a vacuum. The residue is digested with ligroin and filtered off with suction. There are obtained 3.4 g. (85% of theory) of the title compound; m.p. 111°-113° C.
