실험 절차

160 mg of 3-[3-(4-fluorofluorophenyl)-3-hydroxypropyl]-1-(4-hydroxyphenyl)-4-(4-methoxyphenyl)azetidin-2-one (11) were dissolved in 4 ml of absolute dimethylformamide. 210 mg of powdered potassium carbonate and 42 mg of 1,4,-butanesultone were added. The mixture was stirred at room temperature overnight. The reaction solution was concentrated under oil pump vacuum, taken up in dichloromethane and washed 1× with water. The aqueous phase was acidified with 2N hydrochloric acid and extracted 2× with dichloromethane. The combined organic phases were dried over sodium sulfate and concentrated. The residue was chromatographed on a 10 g SiO2 cartridge (dichloromethane/methanol=5/1). The product (72 mg) was obtained as an oil.
