Procedure
With a method similar to that used for the preparation of racemic trans-2-{4′-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-biphenyl-4-carbonyl}-cyclopentanecarboxylic acid above, racemic 2-{4′-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-biphenyl-4-carbonyl}-cyclohexanecarboxylic acid was prepared from 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid and racemic trans-2-(4′-amino-biphenyl-4-carbonyl)-cyclohexanecarboxylic acid. The racemic product obtained was separated by chiral SFC to afford (1S,2S)-2-{4′-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-biphenyl-4-carbonyl}-cyclohexanecarboxylic acid (or enantiomer). [α]D:−23° in DMSO. LCMS calcd for C31H25F3N2O5 (m/e) 562, obsd 563 (M+H).
