Reaction Steps

TFA (2 mL) was added to a solution of 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, 0.14 mmol) in dichloromethane (3 mL) at 20° C. The mixture was stirred at room temperature for 2 hours. LC-MS showed the 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 had disappeared. The reaction mixture was adjusted with a saturated NaHCO3 solution to a pH of around 8-9, then extracted with dichloromethane, and dried with Na2SO4. The organic phase was evaporated, and the residue was purified with prep-HPLC (A: H2O including 0.5% NH3HCO3, B: CH3CN) to afford 1-((1H-indol-6-yl)methyl)-4-(2-(tetrahydro-2H-pyran-4-ylamino)pyrimidin-4-yl)pyridin-2(1H)-one (11 mg, 20% yield). 1H NMR (500 MHz, (CD3)2SO) δ 11.10 (s, 1H), 8.41 (d, J=5.0 Hz, 1H), 7.92 (d, J=7.0 Hz, 1H), 7.50 (d, J=8 Hz, 1H), 7.40-7.32 (m, 3H), 7.15-7.11 (m, 2H), 7.03 (d, J=8 Hz, 1H), 6.85 (d, J=7 Hz, 1H), 6.39 (s, 1H), 5.22 (s, 2H), 3.98 (m, 1H), 3.89-3.85 (m, 2H), 3.45-3.36 (m, 2H), 1.86-1.83 (m, 2H), 1.60-1.45 (m, 2H); LCMS (ESI) m/z: 402.2 [M+H+].
