실험 절차

To a pressure tube were charged tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-iodopyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1-carboxylate (563 mg, 0.8 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(1H-1,2,4-triazol-1-yl)pyridine (287 mg, 1.1 mmol), PdCl2(dppf)2.CH2Cl2 (29 mg, 0.04 mmol), DME (6 mL) and 2M Na2CO3 (2 mL). The resulting mixture was briefly degassed with Argon; the tube was capped, and heated with stirring under 80° C. overnight. After cooling, solvent was removed. The residue was diluted with EtOAc (20 ml), and organic layer was isolated, washed with brine and dried (MgSO4). After concentration under reduced pressure, the residue was purified on silica gel eluting with EtOAc/Hexanes (0-50%) to provide the title compound (370 mg, 64%).
