Reaction Steps

A solution of 3 g of 4-(4-fluoro-benzyloxy)-phenol in 40 ml of 2-butanone was treated with 2.5 g potassium carbonate and 1.6 ml of ethyl bromoacetate. The mixture was stirred at 80° C. during 3 h, then, in order to complete the reaction, 1.7 g of potassium carbonate and 1.9 ml of ethyl bromoacetate were added successively in four portions during a period of 24 h. For the working-up, the reaction mixture was cooled to room temperature, then treated with water and extracted with ethyl acetate. The organic layer was separated, dried over magnesium sulphate and evaporated under reduced pressure. There were obtained 2.95 g (71% of theory) of [4-(4-fluoro-benzyloxy)-phenoxy]-acetic acid ethyl ester as brownish crystals which were pure enough to be used in the next step without further purification; MS: m/e=304 (M)+.
