| Abstract: | 2-Amino-4-methylthio-5-cyano-6(1H)-pyrimidinethione has been prepared via treatment of N-cyanodimethyldithioimidate or 1,1-di(methylthio)-2-thiocar-bamoyl-2-cyanoethylene with cyanothioacetamide or cyanamide. The structure of the complex formed between 2-amino-4-methylthio-5-cyano-6(1H)-pyrimidinethione and urea has been studied by x-ray structural analysis. Thieno2,3-d]pyrimidines and thiazolo3,2-c]pyrimidinium salts have been synthesized based on the 6(1H)-pyrimidinethione.For Communication 25, see 1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1377–1384, October, 1987. |
