A solution of 5.0 g (19.2 mmol) 4-[2-(4-chloro-phenyl)-vinyl]-1-nitro-benzene in 100 ml ethyl acetate is treated with 200 mg of platinum 5% on charcoal. Hydrogenation is performed at room temperature and normal pressure overnight. The catalyst is filtered off and the filtrate evaporated to yield 3.17 g (71%) of a slightly yellow solid. MS: m/e=231.9 (M++H).
