Downstream synthetic route of 165250-69-1

165250-69-1, The synthetic route of 165250-69-1 has been constantly updated, and we look forward to future research findings.

165250-69-1, 4-Methyl-5-nitro-1H-indole is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a cooled solution (ice-water bath) of 4-methyl-5-nitroindole (1.76 g, 10 mmol) in DMF (30 mL) was added KOH pellets (0.78 g, 14 mmol). The cooling bath was removed, and the mixture was stirred at rt for 10 min. Iodine (2.79 g, 11 mmol) was added, and the stirring was continued for 5 h at room temperature. To this mixture was added potassium carbonate (3.17 g, 23 mmol) and methyl iodide (3.1 mL, 50 mmol), and stirring was continued at room temperature for 16 h. The mixture was diluted with water (150 mL), and treated with solid NaHSO3 with stirring until all excess iodine was quenched. The crude product was collected by filtration, washed with plenty of water, and dried.

165250-69-1, The synthetic route of 165250-69-1 has been constantly updated, and we look forward to future research findings.
