반응 단계

To a suspension of (5-bromo-1H-indol-2-yl)-pyrrolidin-1-yl-methanone (0.53 g, 1.8 mmol) in THF (50 mL) at 0° C. was slowly added lithium aluminum hydride (0.20 g, 5.4 mmol). The mixture was stirred under nitrogen at 0° C. for a while and the cooling bath was allowed to warm to room temperature. The mixture was then stirred at room temperature for 17 hours. The reaction was quenched by careful, successive, dropwise addition of water (0.2 mL), 15% NaOH aqueous solution (0.2 mL), and water (0.6 mL). The solid was filtered and washed with MeOH and CH2Cl2. The filtrate was concentrated to dryness, and dried under vacuum, to give 5-bromo-2-pyrrolidin-1-ylmethyl-1H-indole as a white solid. Yield: 0.45 g (90%).
