Abstract
2‐Chloro‐5‐(chloromethyl)‐pyridine reacted with 3,4‐dihydropyrimidin‐2(1H)‐ones 1 to afford 1‐[6‐aryl‐1‐(6‐chloropyridin‐3‐yl‐methyl)‐2‐(6‐chloropyridin‐3‐yl‐methylthio)‐4‐methyl‐1,6‐dihydropyrimidin‐5‐yl] carboxylates or ethanones 2 in good yields. The structure of the target compounds 2 was confirmed by IR, ^1^H NMR, EI‐MS, and elemental analyses, and compound 2a was further characterized by single crystal X‐ray diffraction. The preliminary bioassay indicated that some of the title compounds possess moderate insecticidal and fungicidal activities. J. Heterocyclic Chem., (2011).
