Versuchsvorschrift

To a mixture of 1-(4-fluorobenzyl)-5-methanesulfonylindole-2-carboxamide (100 mg) and dichloromethane (2 ml), triethylamine (0.09 ml) and anhydrous trifluoroacetic acid (0.09 ml) were added at 15 to 30° C. and the mixture was stirred at the same temperature for 2 hours. Water was added therto, and the mixture was extracted with dichloromethane. The organic layer was washed with water, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography (hexane:ethyl acetate=2:1) to obtain 68 mg of the desired product as a white crystal.
