Excerpt from The Synthesis of Some Glyoxaline Derivatives: ThesisBy this means then, glyoxaline, glyoxaline M carboxanilid, and di carboxylic acid are made readily available for the synthesis of glyoxaline deriva tives; and the following scheme was worked out. This carboxanilid on treatment with phosphorus pentachloride would yield the imidchloride, which on treatment with
