Procedure

To (S)-methyl 2-(6-((S)-1,2-dihydroxyethyl)-2-(4-(4-fluorophenoxy)phenyl) pyrimidine-4-carboxamido)propanoate (0.120 g, 0.263 mmol) was added MeOH (2.5 mL) and 7M NH3 in MeOH (2.5 mL, 17.5 mmol). The reaction was sealed, stirred overnight then evaporated in vacuo. MeOH was added and the reaction mixture evaporated again in vacuo. The resulting solid was triturated with 4 mL 20% EtOAc/hexanes, filtered, and rinsed once with 2 mL 20% EtOAc/hexanes. The material was dried under vacuum to give N-((S)-1-amino-1-oxopropan-2-yl)-6-((S)-1,2-dihydroxyethyl)-2-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide (Compound Example No. 16) as a pale peach-colored powder (0.099 g, 0.23 mmol. 87% yield). 1H NMR (400 MHz, DMSO-d6): 8.99 (1 H, d, J=7.7 Hz), 8.55 (2 H, d, J=9.0 Hz), 8.01 (1 H, s), 7.60 (1 H, s), 7.33-7.25 (2 H, m), 7.24-7.17 (3 H, m), 7.14 (2 H, d, J=8.8 Hz), 5.83 (1 H, d, J=5.3 Hz), 4.83 (1 H, t, J=5.9 Hz), 4.70 (1 H, q, J=3.9 Hz), 4.50 (1 H, p, J=7.2 Hz), 3.84-3.77 (1 H, m), 3.71-3.63 (1 H, m), 1.41 (3 H, d, J=7.0 Hz); LC/MS: m/z=441.2 [M+H]+.
