Abstract
Abstract A 1-(2-acylaminophenyl)imidazole of formula: ##STR1## wherein R 5 is hydrogen or an aliphatic, cycloaliphatic, phenyl, substituted phenyl, fused bicyclic aryl or monocyclic aryl substituted aliphatic group bonded to the carbonyl carbon through a carbon-to-carbon linkage. The compounds are useful as intermediates in the preparation of 4-substituted imidazo[1,2-a]quinoxalines.
