摘要:
The present invention relates to a novel process for the preparation of a diastereomeric mixture of piperidinylaminomethyl trifluoromethyl cyclic ether compounds of formulae Ia and Ib: and pharmaceutically acceptable salts thereof, wherein R 1 is C 1 -C 6 alkyl; R 2 is C 1 -C 6 alkyl, halo C 1 -C 6 alkyl or phenyl or substituted phenyl; R 3 is hydrogen or halo; m is zero, one or two, and wherein said mixture is highly enriched in the compound of formula Ia, and to novel processes for the preparation and purification of intermediate compounds useful in the preparation of compounds of formulae Ia and Ib.
