Procedure

12.68 g (47.8 mmol) of 3-fluoro-4-(3-fluoro-benzyloxy)-nitrobenzene in 150 ml ethyl acetate is treated with 1.27 g of 5% platinum on charcoal and hydrogenated for 6 h at room temperature and normal pressure. The catalyst is filtered and the solution evaporated to yield 11.03 g (98%) of dark brown oil. MS: m/e=235.1 (M+).
