Procedure
To an N,N-dimethylformamide (10 ml) solution of 6-carboxy-1-(2-chlorobenzyl)-2-methylindole (0.470 g), added is N,N′-carbonyldiimidazole (0.508 g), and stirred at room temperature for 1 hour. Next, benzenesulfonamide (0.493 g) and diazabicycloundecene (0.477 g) are added thereto, and stirred at 100° C. for 72 hours. The solvent is evaporated away under reduced pressure, and the residue is purified through silica gel column chromatography (eluent: chloroform) to obtain 6-(benzenesulfonylcarbamoyl)-1-(2-chlorobenzyl)-2-methylindole. This is dissolved in a small amount of ethyl acetate, to which is added hexane. The crystal formed is taken out through filtration, and dried to obtain 6-(benzenesulfonylcarbamoyl)-1-(2-chlorobenzyl)-2-methylindole (32) (0.440 g).
