Sodium Hydroxide → 1-Methylindolin-5-amine

関与物質

反応手順

To a solution of 1-methyl-5-nitro-2,3-dihydro-1H-indole (0.2 g, 1.13 mmol) in ethyl acetate (12 ml) was added stannous chloride dihydrate (1.26 g, 5.6 mmol) and the reaction mixture was stirred overnight at room temperature. The reaction was then neutralized with aqueous sodium hydroxide solution. The organic layer was separated, washed with water, dried, and then concentrated to oil. The crude compound was purified by column chromatography over silica gel using ethyl acetate/pet ether (1:1) as eluent to give 1-methyl-2,3-dihydro-1H-indol-5-ylamine (0.12 g, 72%) as solid.
