A microwave reaction vessel was charged with N-{2,5-dichloro-6-[(5-methoxy-1H-pyrazol-3-yl)amino]pyrimidin-4-yl}-N-methylmethanesulfonamide (Method 25, 63.8 mg, 0.174 mmol), (S)-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 7, 61.7 mg, 0.348 mmol), and DIPEA (0.122 ml, 0.693 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 (63.1 mg, 77%). LC-MS: 472 (M+1). 1H NMR (DMSO-d6, 400 MHz) δ 11.71 (s, 1H), 9.40 (s, 1H), 8.77 (s, 2H), 7.91 (s, 1H), 5.65 (s, 1H), 5.07-5.10 (m, 1H), 3.79 (s, 3H), 3.01 (s, 6H), 1.54 (d, 3H).
