A microwave reaction vessel was charged with N-{2,5-dichloro-6-[(5-methoxy-1H-pyrazol-3-yl)amino]pyrimidin-4-yl}-N,N′,N′-trimethylsulfamide (Method 29, 44.1 mg, 0.112 mmol), (S)-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 7, 39.5 mg, 0.223 mmol), and DIPEA (0.062 ml, 0.352 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 (48.6 mg, 87%). LC-MS, 501 (M+1). 1H NMR (DMSO-d6, 400 MHz) δ 12.01 (s, 1H), 9.76 (s, 1H), 8.83 (s, 2H), 8.21 (s, 1H), 5.60 (s, 1H), 5.04-5.06 (m, 1H), 3.76 (s, 3H), 2.80 (s, 3H), 2.70 (s, 6H), 1.59 (d, 3H).
