実験手順

To a solution of (5-chloro-1H-indol-2-yl)-methanol (3.6 g, 0.02 mol), Ce2CO3 (13 g, 0.04 mol) in 100 mL of DMF which was cooled to 0° C., was added methanesulfonyl-ethene (2.1 g, 0.02 mol) in portions. The reaction mixture was stirred at a temperature between 30° C. and 50° C. overnight. Ice-water was then added to the mixture, the precipitate was filtered and dried to give [5-chloro-1-(2-methanesulfonyl-ethyl)-1H-indol-2-yl]-methanol (2 g, yield: 34.7%).
