Reaction Steps

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 dimethylcarbamylchloride (0.055 mL, 0.6 mmol). The mixture was stirred at RT for 1 h 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 C27H31FN6O2: 491.5. NMR (CD3OD): 8.12 (1H, s), 7.37 (1H, m), 7.34 (2H, d, J=8.4 Hz), 7.28 (1H, m), 7.17 (1H, m), 7.16-7.10 (3H, m), 5.88 (1H, s), 4.51 (2H, s), 3.82 (2H, m), 2.94 (2H, m), 2.88 (6H, s), 2.80 (1H, m), 1.86 (2H, m), 1.72 (2H, m) ppm.
