Procedure

To a suspension of sodium hydride (73 mg, w/w=60%, 1.8 mmol) tert-butyl 2-methyl-1H-indole-3-carboxylate (350 mg, 1.5 mmol) in tetrahydrofuran (30 mL) was added benzoyl chloride (250 mg, 1.8 mmol). The reaction solution was stirred at room temperature for 12 hours. The mixture was concentrated to give a residue, which was purified by column chromatography (silica gel, petroleum ether/ethyl acetate=3:1) to give tert-butyl 1-benzoyl-2-methyl-1H-indole-3-carboxylate (440 mg, 88%).
