To a microwave vial was added (S)-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 7, 369 mg, 2.08 mmol), 5-bromo-2-chloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (Method 38, 500 mg, 1.73 mmol), and DIEA (468 mg, 3.8 mmol). Anhydrous n-BuOH (5 mL) was added, and the vial was heated in microwave oven at 165° C. for 5 hours. The reaction mixture was concentrated. The resulting residue was separated by silica gel column to afford desired product (320 mg, 47%). LC-MS, 393 (M+1). 1H NMR δ 12.02 (s, 1H), 8.82 (s, 2H), 7.94 (s, 1H), 7.48 (s, 0.55H), 5.90 (s, 0.41H), 5.09 (s, 1H), 2.19 (m, 3H), 1.49 (m, 3H).
