A series of 2-p-tolylthiopyridine derivatives was directly synthesized via three-componentreactions of chalcones, malononitrile, and 4-methylbenzenethiol catalyzed by Et3N in DMF under microwave irradiation. It is an efficient and promising synthetic strategy to construct 2-thiopyridine skeleton with the advantage of short time, excellent yield, and convenient operation. J. Heterocyclic Chem., (2009)
