反応手順

To a solution of 5-nitro-2,3-dihydro-1H-indole (1 g, 6.09 mmol) in acetone (12 ml) was added powdered potassium hydroxide (1.7 g, 30.45 mmol), followed by methyl iodide (1.2 g, 9.14 mmol) and stirred overnight at ambient temperature. The solvent was evaporated under vacuum to give a residue, to which water was added and the product extracted with ethyl acetate. Drying and concentration of the organic layer yielded 1-methyl-5-nitro-2,3-dihydro-1H-indole (1 g, 92%) as solid.
