The title compound was prepared from tert-butyl 6-(4-amino-2-fluorophenoxy)pyrimidin-4-ylcarbamate (8 mg, 0.025 mmol) and (4-fluorophenylamino)-3-oxopropanoic acid (6 mg, 0.031 mmol, Compound B of Example 1), TBTU (11 mg, 0.034 mmol), and DIPEA (6 μL, 0.030 mmol) using a similar procedure described for the preparation of Compound C, Example 1. Flash chromatography using 1-1.5% MeOH in CH2Cl2 as the eluent gave the title compound as a white solid (10 mg, 80%). 1H NMR (DMSO-d6) δ 10.48 (s, 1H), 10.46 (s, 1H), 10.25 (s, 1H), 8.39 (s, 1H), 7.74-7.77 (m, 1H), 7.62 (d, 1H, J=5.5 Hz), 7.61 (d, 1H, J=4.9 Hz), 7.36-7.30 (m, 2H), 7.17-7.13 (m, 2H), 3.48 (s, 2H), 1.46 (s, 9H); MS (ESI+) m/z 500.12 (M+H)+.
