Reaction Conditions

Reaction Steps

To a solution of hydroxylammonium chloride (891 mg) in dimethylsulfoxide (5 mL) was added sodium hydrogen carbonate (1.29 g), and this mixture was stirred at 50° C. for 75 minutes. Then, a solution of 6-(6-methoxy-2-phenyl-1H-indol-3-ylmethyl)pyridine-2-carbonitrile (435 mg) in dimethylsulfoxide (1.4 mL) was added dropwise thereto, followed by stirring at 50° C. for 24 hours. The reaction mixture was left to be cooled and diluted with water, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to obtain the title compound (504 mg). 1H-NMR (CDCl3) δ ppm: 3.86 (3H, s), 4.40 (2H, s), 5.63 (2H, br s), 6.43-6.69 (1H, br), 6.77 (1H, dd, J=2.2, 8.8 Hz), 6.91 (1H, d, J=2.2 Hz), 7.09-7.15 (1H, m), 7.31-7.40 (2H, m), 7.40-7.49 (2H, m), 7.49-7.60 (3H, m), 7.66-7.74 (1H, m), 8.06 (1H, br s).
