Procedure

Methyl (5S)-5-[5-[{2-[3,5-bis(trifluoromethyl)phenyl]-2-methylpropanoyl}(methyl)amino]-4-(4-fluoro-2-methylphenyl)-2-pyridinyl]-2-methyl-D-prolinate (Intermediate 20, 30 mg, 0.047 mmol) was dissolved in 7N ammonia solution in MeOH (3 ml) and the reaction mixture was stirred for 48 hours at 50° C. The solvent was evaporated affording the title compound (27 mg, 0.043 mmol, 92% yield) as a white solid. 1H NMR (500 MHz, DMSO-d6) δ ppm 8.31 (s, 1 H) 8.04 (s, 1 H) 7.89-7.99 (m, 1 H) 7.60-7.87 (m, 2 H) 7.44 (s, 1 H) 6.90-7.24 (m, 4 H) 4.39-4.60 (m, 1 H) 3.21-3.32 (m, 1 H) 2.53 (s, 3 H) 2.21 (s, 3 H) 1.45 (s, 6 H) 1.38 (s, 3 H) 1.16-2.37 (m, 4 H) The spectrum of the sample consists of a mixture of conformers (broad lines in the spectrum at r.t). The relative stereochemistry syn was confirmed by dipolar correlation between: —CH3(8) at 1.31 ppm and CH(5) at 4.48 ppm. UPLC: Rt 0.75 min (broad peak), m/z 625 [M+H]+. HPLC: Rt 5.06 min.
