TL;DR: In this article, the 2, 3-dihydro-1H-pyrrolo [1, 2-a] indoles with N-bromosuccinimide in protic solvents such as methanol and acetic acid yielded the brominated compounds.
Abstract: Treatment of the 2, 3-dihydro-1H-pyrrolo [1, 2-a] indoles (1 and 7) with N-bromosuccinimide in protic solvents such as methanol and acetic acid yielded the brominated compounds (4 and 8). The reaction of the pyrrolo [1, 2-a] indole-5, 8-diones (9-13) with N-bromosuccinimide in these solvents afforded the adducts (14-18 and 20-21). Debromination of the brominated compounds (5b, 15, 16 and 20) with tri-n-butyltin hydride was also described.
