A solution of 39 parts of intermediate 42, namely 1-[(4-nitrophenyl)phenylmethyl]-1H-imidazole, in 240 parts of ethanol was hydrogenated at 3.105Pa and at room temperature with 20 parts of Raney nickel. After the calculated amount of hydrogen was taken up, the catalyst was filtered off and the filtrate was evaporated, yielding 34.6 parts (99.1%) of 4-[(1H-imidazol-1-yl)phenylmethyl]-benzenamine (interm. 43).
