N-(4-n-butyl-2-nitrophenyl)-2-dimethylaminoacetamide (36 g), prepared as described above, platinum oxide (0.2 g) and ethanol (100 ml) were shaken together in an atmosphere of hydrogen at laboratory temperature and atmospheric pressure until the uptake of hydrogen was complete; 8.2 litres were absorbed. The mixture was filtered and the ethanol evaporated off. The resultant solid was recrystallised from petroleum spirit (b.p. 60°-80° C.) to give N-(2-amino-4-n-butylphenyl)-2-dimethylaminoacetamide (24.0 g), m.p. 63°-66° C.
