Procedure

Methyl (5R)-5-[5-[{2-[3,5-bis(trifluoromethyl)phenyl]-2-methylpropanoyl}(methyl)amino]-4-(4-fluoro-2-methylphenyl)-2-pyridinyl]-2-methyl-D-prolinate (Intermediate 9, 25 mg, 0.039 mmol) was dissolved in 7N ammonia solution in MeOH (3 ml, 21.0 mmol) and the reaction mixture was stirred for 48 hours at 60° C. The solvent was evaporated and the residue was purified by flash chromatography on silica gel (Companion system; eluent:from 99:1 Dichloromethane/MeOH to 95:5 Dichloromethane/MeOH; 12 g cartridge) affording the title compound (16 mg, 0.026 mmol, 65.5% yield) as a white solid.
