Reaction Steps

NaH (60% in oil) (0.006 g, 0.14 mmol) was added to a 0° C. solution of 3-(4-chlorophenyl)-2-(1H-indol-5-yl)quinazolin-4(3H)-one (0.14 mmol) in THF (5 mL). After stirring for 15 min, MeI (0.01 mL, 0.16 mmol) was added, and the reaction was warmed to room temperature for 1 hour. After quenching with H2O, diluting with EtOAc, washing with brine, drying with Na2SO4, and filtering, the mixture was concentrated in vacuo. Purification by flash chromatography on silica gel, eluting with 10% to 70% EtOAc in heptane, afforded the title compound as a white solid (65%). 1H-NMR (300 MHz, DMSO-d6): δ8.18 (d, J=6.8 Hz, 1H), 7.87-7.90 (m, 1H), 7.75 (d, J=7.8 Hz, 1H), 7.66 (s, 1H), 7.57-7.59 (m, 1H), 7.21-7.47 (m, 6H), 7.12 (d, J=7.0 Hz, 1H), 6.4 (d, J=2.9 Hz, 1H), 3.74 (s, 3H). MS (APCI) m/z: 386 (M+H)+.
