Abstract:
The present invention relates to a novel method for preparing (5S)-4-[5-(3,5-di-chlorophenyl)-5-(trifluoromethyl)-4H-isoxazol-3-yl]-2-methyl-benzoic acid, which can preferably be used in the synthesis of (5S)-4-[5-(3,5-dichlorophenyl)-5-(trifluoro-methyl)-4H-isoxazol-3-yl]-N-[2-oxo-2-(2,2,2-trifluoroethylamino)ethyl]-2-methyl-benzamide.
