Abstract
The hydrolysis of 7-cyano derivatives of pyrrolo[1,2-a]imidazole in 85–90% sulfuric acid at 100°C gives amides of pyrroloimidazole-7-carboxylic acids. Under more severe conditions, the resulting carboxylic acids are decarboxylated to the corresponding pyrroloimidazole derivatives with a free 7 position.
