Reaction Steps

To the solution of crude N-(5-cyclopropyl-1H-pyrazol-3-yl)-2-phenyl-5-((trimethylsilyl)ethynyl) pyrimidin-4-amine in MeOH (3 mL), 20% NaOH was added until the pH was adjusted to 12. After stirring at rt for 15 min, the reaction mixture was evaporated to dryness and purified by silica gel chromatography (hexane/EtOAc=3:1-1:1 as eluent) to afford N-(5-cyclopropyl-1H-pyrazol-3-yl)-5-ethynyl-2-phenylpyrimidin-4-amine (Compound 14) (71 mg, 48%). LC-MS (m/z): 302.1 [M+H]+. 1H NMR (300 MHz, DMSO-d6): δ 0.71-0.76 (m, 2H), 0.94-1.01 (m, 2H), 1.90-1.99 (m, 1H), 6.18-6.28 (bs, 1H), 7.06-7.10 (bs, 1H), 7.51-7.53 (m, 3H), 8.34-8.39 (m, 3H), 9.86 (s, 1H), 12.10 (s, 1H).
