実験手順

To a solution of 5-(3,3-difluoropiperidin-1-yl)-1-(2-((trimethylsilyl)methoxy)ethyl)-1H-pyrazol-4-amine (1.2 g, 3.61 mmol) in 30 mL THF was added DIPEA (1.3 mL, 7.22 mmol) and pyrazolo[1,5-a]pyrimidine-3-carbonyl chloride (720 mg, 3.97 mmol) in THF (50 mL) at 0° C. After addition was complete, the mixture was warmed to room temperature, then stirred overnight. The mixture was concentrated in vacuo and the residue was purified by silica gel column chromatogaphy (hexanes:EtOAc=3:1 to 1:1) to afford 1.0 g (60%) of N-(5-(3,3-difluoropiperidin-1-yl)-1-(2-((trimethylsilyl)methoxy)ethyl)-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. LCMS (ESI) m+H=478.2; 1H NMR (400 MHz, CDCl3) δ: 9.49 (s, 1H), 8.87 (dd, 1H), 8.75 (s, 1H), 8.71 (dd, 1H), 7.94 (s, 1H), 7.10 (dd, 1H), 5.40 (s, 2H), 3.67 (m, 6H), 2.06 (s, 2H), 1.93 (m, 2H), 0.95 (m, 2H), 0 (s, 9H).
