Procedure
A solution of (S)-methyl 2-((4-carbamoyl-6-(4-(4-fluorophenoxy)phenyl)pyrimidin-2-yl)amino)propanoate (0.911 g, 2.22 mmol) in 7M ammonia in methanol (20 mL, 140 mmol) was heated in a sealed tube for 4 days at 50° C. After cooling, the reaction mixture was evaporated in vacuo and the residue chromatographed over silica gel with 50-100% acetone in hexanes. The product fractions were evaporated in vacuo and the resulting solid triturated with 10 mL 1:1 acetone/hexanes. The solid was filtered, rinsed once with 5 mL 1:1 acetone/hexanes, and dried under vacuum at 40° C. to give (S)-2-((1-amino-1-oxopropan-2-yl)amino)-6-(4-(4-fluorophenoxy)phenyl)pyrimidine-4-carboxamide as a white powder (0.713 g, 1.80 mmol, 81% yield). 1H NMR (400 MHz, CD3OD): 8.20 (2H, d, J=8.8 Hz), 7.76 (1H, s), 7.21-7.08 (4H, m), 7.06 (2H, d, J=8.8 Hz), 4.47 (1H, br s), 1.54 (3H, d, J=7.2 Hz). LC/MS: m/z=396.1 [M+H]+.
