Syntheses of thieno[2,3-d]pyrimidines and aminopyreviedines from 2-alkoxy-5-cyano-4-thioxopyreviidine intermediates

β-Chloro-α-cyanocinnarnonitrile reacts in an one-pot reaction with potassium thiocyanate and alkanol to form 2-alkoxy-6-phenyl-5-cyano-l,4-dihydro-4-pyrimidinthions. The products were S-alkylated to yield thieno[2,3-d]pyrimidines on cyclization and aminopyrimidines on substitution of alkoxy and alkylthio groups.
