Sodium hydride (58 mg) was added to a solution of benzyl 1H-indole-5-carboxylate (300 mg) in N,N-dimethylformamide (2 ml) with ice cooling, and then stirred for 30 minutes. Benzoyl chloride (202 mg) was added thereto, and the mixture was stirred for 2 hours. The reaction mixture was diluted with dichloromethane, and the organic phase was washed with 2 N hydrochloric acid, a saturated sodium bicarbonate solution and a saturated saline solution. The organic phase was dried over sodium sulfate anhydrous. The product was concentrated under reduced pressure to give benzyl 1-benzoyl-1H-indole-5-carboxylate (500 mg, Y.:quant.) as pale orange crystals.
