Procedure

KOt-Bu (180 mg, 1.6 mmol) and n-Bu4NI (37 mg, 0.1 mmol) were added to a mixture of tert-butyl 6-((methylsulfonyloxy)methyl)-1H-indole-1-carboxylate (0.8 mmol) and 4-(2-((tetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-2(1H)-one (164 mg, 0.6 mmol) in anhydrous THF (15 mL). The resulting mixture was stirred at 70° C. under microwave irradiation for 2 hours. LC-MS showed the tert-butyl 6-(((methylsulfonyl)oxy)methyl)-1H-indole-1-carboxylate had disappeared. The reaction mixture was treated with water (20 mL) and diluted with dichloromethane. After removal of the insolubles by filtration, the filtrate was extracted with dichloromethane. The combined organic phase was dried with Na2SO4 and concentrated. The residue was purified with Combiflash (A: H2O including 0.5% NH3HCO3, B: CH3CN) to afford tert-butyl 6-((2-oxo-4-(2-((tetrahydro-2H-pyran-4-yl)amino)pyrimidin-4-yl)pyridin-1(2H)-yl)methyl)-1H-indole-1-carboxylate (70 mg, 23% yield).
