Abstract
2-Amino-3-cyano-4-N-arylcarbamoyl-5-methylthiophenes were obtained by condensation of arylamides of acetoacetic acid with sulfur and malononitrile in absolute alcohol. 4-Amino-6-N-arylcarbamoyl-5-methylthieno [2,3-d]pyrimidines are formed by reaction of the condensation products with formamide.
