Procedure

Compound 4-(2-fluorobenzylamino)-6-(4-(piperidin-4-yl)phenylamino)nicotinamide (Example 106) HCl salt (100 mg, 0.2 mmol) was stirred in 5 mL NMP. To the solution were added DIEA (0.18 mL, 1.0 mmol) and acetyl chloride (0.022 mL, 0.3 mmol). The mixture was stirred at RT for 15 min and quenched with Me2NH. The mixture was concentrated in vacuo and subjected to reverse phase prep HPLC to isolate the title compound as HCl salt. UV=259 nm. M+H found for C26H28FN5O2: 462.5. NMR (CD3OD): 8.12 (1H, s), 7.37 (1H, m), 7.34 (2H, d, J=8.4 Hz), 7.28 (1H, m), 7.18 (1H, m), 7.15-7.10 (3H, m), 5.88 (1H, s), 4.69 (1H, m), 4.51 (2H, s), 4.06 (1H, m), 3.24 (1H, m), 2.89 (1H, m), 2.73 (1H, m), 2.15 (3H, s), 1.92 (2H, m), 1.66 (2H, m) ppm.
