N4-(4-{[2-(Aminomethyl)pyridin-4-yl]oxy} phenyl)-6-phenylpyrimidine-2,4-diamine (50 mg, 0.13 mmol, Example 39) and diethylcarbamyl 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 that the reaction was complete. 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 72 mg of the crude product. The residue was purified by Prep-TLC (CH3OH:EtOAc=2:8) to obtain 40 mg (63%) of the title product as a yellowish oil. 1H NMR (CD3OD) δ 8.28 (d, 1H), 7.84 (m, 3H), 7.81 (s, 1H), 7.48 (m, 3H), 7.05 (d, 2H), 6.84 (m, 1H), 6.75 (s, 1H), 6.44 (s, 1H), 4.39 (s, 2H), 3.23 (m, 4H), 1.20 (t, 6H); MS ES 484 (M+H)+, calcd 484, RT=2.37 min; TLC (MeOH/EtOAc=20/80) Rf=0.4
