A solution of 4-chloro-6-(2-amino-2-fluorophenoxy)pyrimidine (29 mg, 0.12 mmol, Compound B of Example 2), 3-(4-fluorophenylamino)-3-oxopropanoic acid (26 mg, 0.13 mmol, Compound B of Example 1) in DMF (1.5 mL) was treated with DIPEA (24 μl, 0.14 mmol) and TBTU (46 mg, 0.14 mmol). The reaction mixture was stirred at RT overnight, diluted with EtOAc (25 mL), and the organic phase was washed with brine (3×20 mL), dried (MgSO4) and concentrated. The product was purified by flash chromatography using 1-3% MeOH in CH2Cl2 as the eluent to give the title compound as a white solid (35 mg, 78%). 1H NMR (DMSO-d6) δ 10.49 (s, 1H), 10.25 (s, 1H), 8.65 (s, 1H), 7.78 (d, 1H, J=12.1 Hz), 7.63-7.57 (m, 3H), 7.40-7.34 (m, 2H), 7.16 (t, 2H, J=8.8 Hz), 3.48 (s, 2H); MS(ESI+) m/z 419.21 (M+H)+.
