N4-(4-{[2-(Aminomethyl)pyridin-4-yl]oxy}phenyl)-6-phenylpyrimidine-2,4-diamine (50 mg, 0.13 mmol, Example 39) and 4-fluorobenzoyl chloride (20.6 mg, 0.13 mmol) were suspended in THF (1 mL) and stirred at rt for 24 h. TLC and LC-MS indicated the reaction was completed. The mixture was extracted with EtOAc and washed with 1N aqueous sodium hydroxide solution (2×) and H2O (3×). The organic layer was dried and concentrated to give 68 mg of the crude product. The residue was purified by Prep-TLC (CH3OH:EtOAc=2:8) to obtain 38 mg (58%) of the title product as a yellowish oil. 1H NMR (CD3OD) δ 8.34 (d, 1H), 7.82 (m, 4H), 7.78 (d, 2H), 7.44 (m, 3H), 7.15 (t, 2H), 7.02 (d, 2H), 6.85 (d, 1H), 6.82 (s, 1H), 6.42 (s, 1H), 4.59 (s, 2H); MS ES 507 (M+H)+, calcd 507, RT=2.50 min; TLC (MeOH/EtOAc=20/80) Rf=0.57.
