Reaction Steps

A mixture of 5-bromo-2-chloro-N-(5-isopropoxy-1H-pyrazol-3-yl)pyrimidin-4-amine (Method 13, 150 mg, 0.45 mmol), (S)-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 7, 88 mg, 0.5 mmol) and DIPEA (0.12 ml) in n-BuOH (2 ml) was charged into a microwave reaction vessel. The vessel was sealed and heated in microwave reactor at 165° C. for 4 hours. The solvent was removed under reduced pressure and the residue was purified by flash chromatography on silica gel (20-60% EtOAc in hexanes) to give the titled compound as solid (118 mg, 60%). NMR: 11.98 (s, 1H), 9.36 (s, 1H), 8.82 (s, 2H), 8.10 (s, 1H), 7.96 (s, 1H), 5.56 (s, 1H), 5.13 (s, 1H), 4.66 (m, 1H), 1.48 (m, 3H), 1.26 (m, 6H); m/z 437.
