Versuchsvorschrift

A mixture of 141 parts of 3-{[2-nitro-4-(trifluoromethyl)phenyl]amino}-1-propanol and 1200 parts of methanol is hydrogenated at normal pressure and at room temperature with 15 parts of Raney-nickel catalyst. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated. The residue is crystallized from 2,2'-oxybispropane, yielding 110 parts (100%) of 3-{[2-amino-4-(trifluoromethyl)phenyl]amino}-1-propanol.
