실험 절차
An amount of 44.3 gm (0.2 mol) of the p-nitrobenzoic acid dipropylamide from step (a) was dissolved in 500 ml of ethanol and, after addition of 5 gm of palladium active charcoal (5%), hydrogenated at 50° C. and 60 bar pressure. After filtration, evaporation of the ethanol solution, and recrystallization of the residue (34.1 gm) from ether, 26.7 gm of p-aminobenzoic acid dipropylamide with a melting point of 78°-79° C. were obtained.
