Abstract

Abstract The 5-cyano-6-aryl-2-thiouracils 1a–d were prepared 1, 2) for the syntheses of several other pyrimidine derivatives. In basic medium 1a reacted with picryl chloride yielding the unexpected benzothiazolo-pyrimidine 2. Heating a mixture of 1 and 1, 2-dibromoethane in DMF in basic medium gave the thiazolopyrimidines 3a, d, while the reaction of 1 with 1, 3- dibromopropane and 1, 3-dibromo-2-propanol under similar conditions yielded the ...
