摘要
The synthesis of 5-acetyl-2-cyanoimino-6-methyl-4-phenyl-1,2,3,4-tetrahydropyrimidine has been carried out by reaction of N-[(tosyl)(phenyl) methyl]-N'-cyanoguanidine with acetylacetone in the presence of sodium hydride with subsequent acid catalyzed dehydration of the 4-hydroxy-2-imino-hexahydropyrimidine obtained. The oxidative aromatization of the tetrahydropyrimidine synthesized using manganese dioxide has been studied. It was found that the products formed depend on the reaction temperature and are either 5-acetyl-2-carbamoylamino-4-methyl-6-phenylpyrimidine or 5-acetyl-2-amino-4-methyl-6-phenylpyrimidine or a mixture of both.
