Abstract
A process for the preparation of 2-substituted 5-chloroimidazole-4-carbaldehydes of the general formula: ##STR1## in which glycine is reacted with an imido ester of the general formula: ##STR2## and the resultant intermediate is converted into the product by a Vilsmeier reagent. The 2-substituted 5-chloroimidazole-4-carbaldehydes are valuable intermediates for the preparation of pharmaceuticals or herbicidally active compounds.
