Abstract A novel and efficient method for the synthesis of N-aryl-6-methylsulfanyl-4-oxopyrimidine-5-carbonitriles via the reaction of dimethyl N-cyanodithioiminocarbonate with substituted cyanoacetanilides has been investigated. (3)N-Aryl-2,5-diamino-7H-pyrazolo[3,4-d]-pyrimidin-4(3H)-one have also been prepared from the reaction of 6-sulfanylthio-N-aryl-4-pyrimidinones with hydrazines.
