To a solution of 2-(4-(Diethoxyphosphoryl)phenyl)-2-phenylacetic acid, 14-f, (1.18 g, 3.4 mmol), HATU (1.86 g, 4.9 mmol) and triethylamine (989 mg, 9.8 mmol) in CH3CN (20 mL) was added 5-amino-2-(1H-pyrazol-1-yl)pyrimidin-4-ol (11-e, 577 mg, 3.30 mmol). The mixture was stirred at room temperature overnight and concentrated. The residue was taken up in EA and water. The aqueous layer was extracted with EA. The combined layers were washed with brine, dried over Na2SO4, and concentrated to give the crude product of 14-1 which was purified by pre-HPLC (766 mg, 45%). 1H NMR (300 MHz, DMSO-d6) δ1.18-1.23 (m, 6H), 3.92-4.03 (m, 4H), 6.64 (s, 1H), 7.25-7.35 (m, 6H), 7.47-7.51 (m, 2H), 7.64-7.71 (m, 2H), 7.97 (s, 1H), 8.61-8.52 (m, 1H), 8.63 (br s, 1H); LC-MS: (M+H)+ 508.
