摘要

A series of substituted diheteroaryl sulfides was synthesized by the reaction of 4,6-diaminopyrimidine-2(1H)-thione with fluoro- and chloroheteroaromatic compounds in the presence of Na2CO3 in acetonitrile under reflux conditions. Our study indicated that 4,6-diaminopyrimidine-2(1H)-thione reacts with fluoro- and chloroheteroaromatic compounds chemoselectively as S- rather than N-nucleophile. The structures of the synthesized compounds were confirmed by IR, H-1, F-19, and C-13 NMR spectroscopy, as well as elemental analysis and X-ray structural analysis.
