A solution of 242 mg (1.77 mmol) chlorocarbonyl-acetic acid methyl ester in 2 ml dichloromethane is added dropwise to an ice-cooled solution of 350 mg (1.61 mmol) 4-(3-fluoro-benzyloxy)-phenylamine in 7 ml of pyridine. The mixture is then stirred for 2 h at room temperature, diluted with water, acidified with dil. hydrochloric acid and extracted with ethyl acetate. The organic phase is dried. Chromatography (silica gel, ethyl acetate/hexane 1:1) yields 99 mg (19%) of the title compound. Yellowish solid; MS: m/e=418.1 (M++H).
