It has been shown by KlaberZ that when acetanthranils condense with primary aliphatic diamines the reaction is a complicated one, resulting in the formation of at least three distinct products, but no appreciable amount of the aminoalkylquinazolone. We were, therefore, somewhat surprized to discover that when aromatic primary diamines are condensed with acylanthranils under proper conditions, not only is the reaction a remarkably smooth and ...
