Reaction Steps

A microwave reaction vessel was charged with N-{2,5-dichloro-6-[(5-methyl-1H-pyrazol-3-yl)amino]pyrimidin-4-yl}-N,N′,N′-trimethylsulfamide (Method 24, 83.9 mg, 0.221 mmol), (S)-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 7, 78.4 mg, 0.443 mmol), and DIPEA (0.120 ml, 0.682 mmol). Anhydrous n-BuOH (1 ml) was added, and the tube was sealed and heated in a microwave reactor at 160° C. for 2 hours. The reaction mixture was purified by silica gel chromatography (by ISCO Combiflash with gradient EtOAc and hexane) to afford the title compound as a white solid (95.8 mg, 89.6%). LC-MS, 485 (M+1). 1H-NMR (DMSO-d6, 400 MHz, 80° C.) δ 11.48-12.40 (br, 1H), 8.77 (s, 1H), 7.85-8.66 (br, 1H), 6.98-7.61 (br, 1H), 6.23 (s, 1H), 5.14-5.11 (m, 1H), 2.93 (s, 3H), 2.83 (s, 6H), 2.21 (s, 3H), 1.53 (d, 3H).
