Syntheses of 2,3-Dihydro-5H-thiazolopyrimidines and Tetrasubstituted Dihydropyrimidine Derivatives as Possible Anthelmintic Agents

The hitherto unreported ring closure reaction of 5-ethoxycarbonyl-6-methyl-4-substitutedphenyl-3,4-dihydropyrimidine-2-thione with monochloroacetic acid in the presence of BF3-etherate is described.The reaction appears to have a general applicability and
