実験手順

A mixture of 4-(3,5-difluorophenoxy)phenol (11.1 g, 50.0 mmol), ethyl 2-bromopropionate (9.96 g, 55.0 mmol), potassium carbonate (7.25 g, 52.5 mmol) and N,N-dimethylformamide (50 ml) was stirred at an inner temperature of 70° to 80° C. for 3 hours. After allowed to cool, the reaction mixture was poured into ice-water and extracted with toluene. The toluene layer was dried over anhydrous magnesium sulfate, and the solvent was removed to give ethyl 2-[4-(3,5-difluorophenoxy)phenoxy]propionate (15.6 g).
