REACTIONS OF 1-SUBSTITUTED BENZO[4,5]IMIDAZO[1,2-<i>a</i>]PYRIDINES
Keywords:
benzo[4,5]imidazo[1,2-a]pyridine, acylation, brominationAbstract
Bromination of 1-oxo(imino, amino)benzo[4,5]imidazo[1,2-a]pyridines gave the corresponding 2-bromo derivatives. Acylation using the Vilsmeier complex in acetic anhydride gave the N-formyl and N-acetyl derivatives. The reaction of the amine with the Vilsmeier complex, acetyl acetone, ethyl acetoacetate, and 2,5-dimethoxytetrahydrofuran occurs at the amino group.
