Abstract
A series of 2,4-diamino-6-hydroxy-5-arylazopyrimi-dines and 1,3-dimethyl-5-arylhydrazonoalloxans has been synthesized by the coupling of aryldiazonium salts with 2,4-diamino-6-hydroxypyrimidine and 1,3-dimethylbarbituric acid, respectively. The former are also obtained by the cyclization of ethyl cyano-glyoxalate arylhydrazones and guanidine hydrochloride in the presence of sodium ethoxide.
