A microwave reaction vessel was charged with 1-(5-fluoropyrimidin-2-yl)ethanamine (Method 1, 0.25 g, 1.77 mmol), 2,5-dichloro-N-(5-isopropoxy-1H-pyrazol-3-yl)pyrimidin-4-amine (Method 2, 0.50 g, 1.77 mmol), and DIPEA (0.30 g, 2.34 mmol). Anhydrous n-BuOH (2 ml) was added, and the tube was sealed and heated in a microwave reactor at 160° C. for 10 hours. The reaction mixture was purified by silica gel chromatography twice (by ISCO Combiflash with gradient EtOAc and DCM) to afford the title compound as a white solid (0.19 g, 27%). LC-MS, 393 (M+1). 1H NMR (CDCl3) δ 8.50 (s, 2H), 7.75 (s, 1H), 5.50 (s, 1H), 5.20 (m, 1H), 4.68 (m, 1H), 1.55 (d, 3H), 1.20 (d, 6H).
