RESOLUTION OF (±)-METHYL PHENYL[4-[4-[[[4'(TRIFLUOROMETHYL)-2- BIPHENYLYL]CARBONYL]AMINO]PHENYL]-1-PIPERIDINYL]ACETATE

摘要

The present invention relates to a resolution process of (±)-methyl phenyl[4-[4-[[[4′-(trifluoromethyl)-2-biphenylyl]carbonyl]amino]phenyl]-1-piperidinyl]acetate to isolate the MTP (microsomal triglyceride transfer protein) inhibitor methyl (2S)-phenyl[4-[4-[[[4′-(trifluoromethyl)-2-biphenylyl]carbonyl]amino]phenyl]-1-piperidinyl]acetate and an epimerisation procedure for racemizing methyl (2R)-phenyl[4-[4-[[[4′-(trifluoromethyl)-2-biphenylyl]carbonyl]amino]phenyl]-1-piperidinyl]acetate.
