Provided are processes for purifying (3R,4S)-4-(4-hydroxyprotected-phenyl)-1-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3-oxopropyl]azetidin-2-one having the following formula II
wherein X and Y are hydrogen or a substituted or unsubstituted C
1-8
alkyl; n is an integer between 0 and 3; and P is a hydroxyl protecting group. The Compound of formula II may be converted to an azetidinone compound, which is useful, for example, in reducing cholesterol in mammals.
提供了一种用于纯化(3R,4S)-4-(4-羟基保护苯基)-1-(4-氟苯基)-3-[3-(4-氟苯基)-3-氧代丙基]氮杂二环-2-酮的方法,该化合物具有以下化学式II,其中X和Y是氢或取代或未取代的C1-8烷基;n是介于0和3之间的整数;P是羟基保护基。化合物II可以转化为氮杂二环酮化合物,例如在降低哺乳动物胆固醇方面有用。
