To a solution of 5-chloro-2-phenylindole (154 mg) in N,N-dimethylformamide (1.5 mL) was added sodium hydride (dispersed in liquid paraffin, minimum 55%, 31 mg) at room temperature, and the mixture was stirred for 15 minutes. Methyl 6-(chloromethyl)pyridine-2-carboxylate (126 mg) was added and this resulting mixture was stirred at 50 to 60° C. for additional 18 hours. Water, ethyl acetate and a saturated aqueous ammonium chloride solution were added to the reaction mixture. The organic layer was separated. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed successively with water and saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by aminopropylated silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (112 mg).
