Procedure

A solution of 7.3 g (30 mmol) of 4-[2-(4-fluoro-phenyl)-vinyl]-1-nitro-benzene in 250 ml of ethanol is treated with 80 ml of aqueous 25% hydrochloric acid. The mixture is heated at 110° C. and 5 g (42 mmol) of tin is added portionwise. After stirring for 3 h at 110° C. the suspension is cooled to room temperature, neutralised by additon of aqueous sodium hydroxide and extracted 3 times with dichloromethane. Drying over magnesium sulfate and evaporations yields 5.46 g (85%) of a colorless solid. MS: m/e=214.2 (M++H).
