Procedure
A mixture of 43 parts of N-(1-methylethyl)-N'-(2-nitrophenyl)-N-[1-(2-phenylethyl)-4-piperidinyl]thiourea and 800 parts of methanol, saturated with ammonia is hydrogenated at normal pressure and at room temperature with 6 parts of palladium-on-charcoal catalyst 10% and 6 parts of platinum-on-charcoal catalyst 5%. After the calculated amount of hydrogen is taken up, the catalysts are filtered off over Hyflo and the filtrate is evaporated, yielding 39 parts (100%) of N-(2-aminophenyl)-N'-(1-methylethyl)-N'-[1-(2-phenylethyl)-4-piperidinyl]thiourea as a residue.
