Procedure

To a solution of 5-methoxy-2-phenyl-1H-indole (200 mg) in N,N-dimethylformamide (5 mL) was added sodium hydride (dispersed in liquid paraffin, 50% or more, 45 mg) under ice-cooling. This mixture was stirred for 30 minutes at room temperature. Subsequently, 6-chloromethylpyridine-2-carbonitrile (216 mg) was added thereto, followed by stirring at 80° C. overnight. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (228 mg). 1H-NMR (DMSO-d6) δ ppm: 3.77 (3H, s), 5.55 (2H, s), 6.55-6.65 (1H, m), 6.77 (1H, dd, J=2.4, 8.8 Hz), 6.91 (1H, dd, J=1.5, 7.4 Hz), 7.13 (1H, d, J=2.4 Hz), 7.26 (1H, d, J=8.8 Hz), 7.35-7.55 (5H, m), 7.85-7.95 (2H, m).
