Abstract
A process for the preparation of 2-quinoxalincarboxamide-l, 4-dioxides, characterized by reacting a benzofuroxane with at least equimolar proportions of a pyruvic acid ester and a compound selected from the group consisting of ammonia, a primary amine and a secondary amine; and wherein the pyruvic acid amide can be used, in which case a basic catalyst is present.
