Reactions of 5-acetyl-1-aryl(alkyl)-6-methyl-4-methylsulfanylpyrimidine-2(1H)-thiones (prepared from diacetylketene N,S-acetal) with guanidine afforded 3-alkyl- and 3-aryl-7-amino-5-methyl-4-methylidene-3,4-dihydropyrimido[4,5-d]pyrimidine-2(1H)-thiones. By-products of these reactions (5-acetyl-1-alkyl(aryl)-6-methyl-2-thiouracils) can also be obtained from the starting pyrimidinethiones and EtONa in EtOH. Pyrimidopyrimidinethiones can react with MeOH at the methylidene group in the presence of MeONa.
