実験手順

To a solution of 5-chloro-7-fluoro-2-pyridin-3-yl-1H-indole (Example 86, 276 mg, 1.12 mmol) in DMF (4 mL) is added 60% sodium hydride in mineral oil (120 mg, 3.0 mmol) and the suspension is stirred for 30 min. Iodomethane (213 mg, 1.5 mmol) is then added to the reaction mixture and stirred at ambient temperature for 1 h. Water (2 mL) is added to quench the reaction. The mixture is filtered and purified by HPLC using Xbridge C18 with a gradient of acetonitrile in 0.1% NH4OH to afford 5-chloro-7-fluoro-1-methyl-2-pyridin-3-yl-1H-indole. MS (ESI) m/z 261 (M+H)+.
