Methyl iodide → 1H-Indole, 1-methyl-5-nitro-

Participants

Reaction Steps

To a stirred suspension of sodium hydride (5.0 g; 167 mM) in dimethylformamide (200 ml) at 0° C. under nitrogen was added 5-nitroindole (25 g; 154 mM) in dimethylformamide. After stirring for 0.5 h, iodomethane (10.5 ml; 168 mM) in dimethylformamide (50 ml) was added, and stirring was continued for 2 h. The reaction mixture was then quenched with water, and poured onto excess water with stirring. Filtration afforded the title compound (27.4 g; 94%).
