1-Acetyl-5-bromoindoline is a valuable organic compound and could be used to synthesise 5-bromoindoline, 5-Bromo-7-nitroindoline, and others.
| [Synthesis]
The synthesis method of 1-Acetyl-5-bromoindoline is as follows: add acetyl chloride (5.5 mmol, 1.1 equiv) to a stirred solution of 5-Bromoindolin (5 mmol, 1.0 equiv) and Et3N (7.5 mmol,1.5 equiv) in CH2Cl2 (15 mL) at 0°C. Stir the resulting mixture for 1 h under N2 atmosphere. Quench the reaction with NaHCO3 solution (20 mL). Separate the aqueous layer and wash with DCM (15 mL) and combine the organic layers. Dry the organicsolution over anhydrous Na2SO4 and evaporate under vacuum. Purify the residue by column chromatography on silica gel.
