4-[2-(3,4-dichlorophenyl)ethenyl]nitrobenzene (34.0 g, 116 mmol) and 2 g of Raney nickel in 510 ml of tetrahydrofuran were shaken under hydrogen at 15 psi (103.4 kPascal) until four equivalents of hydrogen were consumed. The catalyst was removed by filtration, and the resulting filtrate evaporated in vacuo to yield a residual tan solid. Recrystallization from hexane yielded 26.6 g (86%) of 4-[2-(3,4-dichlorophenyl)ethyl]benzenamine, mp 72°-74° C.
