These common heterocyclic compound, 19727-83-4, name is 6-Nitroindoline, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Safety of 6-Nitroindoline
1-Methyl-2,3-dihydro-1H-indol-6-ylamine. 6-Nitroindoline (2 mmol) was combined with methyl iodide (2.2 mmol), n-Bu4I (7.4 mg, 0.020 mmol), and K2CO3 (350 mg, 2.5 mmol) in acetone (10 mL). The mixture was stirred at 25 C. for 16 h. The mixture was partitioned between CH2Cl2 and satd. aq. NaHCO3 (20 mL), and the organic layer was dried and concentrated. Purification by silica gel chromatography provided 1-methyl-6-nitroindoline (300 mg, 84%).
The synthetic route of 6-Nitroindoline has been constantly updated, and we look forward to future research findings.
