摘要:
The invention relates, in general, to an improved process for the preparation of the compounds (3R,4S)-4-(4-(benzyloxy)phenyl)-l-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3- oxopropyl]azetidin-2-one and (3R,4S)-l-(4-fluorophenyl)-3-[3-(4-fluorophenyl)-3-oxopropyl]- 4-(4-hydroxyphenyl)-azetidin-2-one, which are key intermediates for the synthesis of ezetimibe, as well as the use of these intermediates for the preparation of ezetimibe.
