5-溴-6-甲氧基-1H-吲哚

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The 1-methylsulphonylindole (D19, 21.2 g, 69.7 mmol) was heated under reflux in a mixture of 10% aqueous sodium hydroxide solution (170 ml) and ethanol (1.0 L) for 1.5 h. The mixture was evaporated almost to dryness, and the residue was dissolved in ethyl acetate and washed with water. The organic phase was dried and evaporated to give the title compound (15.65 g, 99%), mp 110-111° C. The mixture was evaporated almost to dryness the residue was dissolved in ethyl acetate washed with water The organic phase was dried evaporated
