반응 단계

1,1-Difluoro-2,2-dimethyl-3-[3-(N-phenyl-N-acetylamino)-4fluorobenzyloxy]propane (0.5 g) was suspended in a 1 molar solution of potassium hydroxide in water containing 20% by volume ethanol and the mixture was heated at the reflux temperature for 8 hours. After standing overnight at the ambient temperature, the mixture was shaken several times with ethyl acetate and the combined organic extracts washed with water and brine, and dried over anhydrous magnesium sulphate. Evaporation of the solvent under reduced pressure gave a brown oil which was purified by column chromatography on a silica gel supoort, eluting with petroleum ether (boiling range 40°-60° C.) containing 10% by volume ethyl acetate, to give the title compound (0.23 g) as a pale yellow oil.
