실험 절차

To a solution of 2-[3-methyl-1-[benzenesulfonyl)indol-2-yl]ethanol (7.1 g) and triethylamine (2.96 g) in dichloromethane (71 ml) was added dropwise methanesulfonyl chloride (2.84 g) in dichloromethane (57 ml) at -40° C. After being stirred at the same temperature for 30 minutes, the reaction mixture was diluted with chilled water, and neutralized with 1N-hydrochloric acid. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and evaporated in vacuo to give 2-[2-(methanesulfonyloxy)ethyl]-3-methyl-1-(benzenesulfonyl)indole (8.8 g) as amorphous powder.
