Synthesis and antimicrobial screening of some substituted INH and THPHM linked pyrimidines
Several 6-(substituted)-5-cyano-2-methylthio-3-N-methyl-3,4- dihydropyrimidin-4-ones (1a-e) were treated with isonicotinic acid hydrazide and 4-anisyl-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carbohydrazide to get (2a-d) and (3a-d). Compounds were ch
