Procedure

To a mixture of 1-(4-fluorophenyl)-2-oxopyrrolidine-3-carboxylic acid (0.3 mol), 4-(4-amino-2-fluorophenoxy)pyridin-2-amine (Compound B of Example 24, 21.9 mg, 0.1 mmol) in DMF (0.5 ml), was added HATU (76 mg, 0.2 mmol) and followed by diisopropylethylamine (0.1 mL, 0.57 mmol). The reaction mixture was stirred at room temperature overnight and was then quenched with 2 mL of methanol. The reaction mixture was purified by prep HPLC. The desired fractions were combined, neutralized with sat. aq. NaHCO3 solution, and concentrated in vacuo to afford the title compound (18 mg, 43%) as a white solid. 1H NMR (DMSO-d6) δ 10.76 (br s, 1H), 7.95 (d, 1H, J=7.2 Hz), 7.91 (m, 1H), 7.68 (m, 2H), 7.50 (m, 1H), 7.44 (t, 1H, J=10.0 Hz), 7.24 (m, 2H), 6.70 (m, 1H), 6.11 (d, 1H, J=2.8 Hz), 3.91 (m, 2H), 3.78 (t, 1H, J=5.0 Hz), 2.41 (m, 2H); MS(ESI+) m/z 425.15 (M+H)+.
