Procedure

A mixture of 34.6 parts of 3-[(4-chloro-2-nitrophenyl)amino]-1-propanol and 320 parts of ethanol is hydrogenated at normal pressure and at room temperature with 8 parts of Raneynickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 30 parts of 3-[(2-amino-4-chlorophenyl)amino]-1-propanol as an oily residue.
