A mixture of 70 parts of 3-[(4-methyl-2-nitrophenyl)amino]-1-propanol and 400 parts of methanol is hydrogenated at normal pressure and at room temperature with 10 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated, yielding 54 parts (91%) of 3-[(2-amino-4-methylphenyl)amino]-1-propanol as a residue.
