摘要
Reaction of N,N'-bis(2-pyridinyl, 3-pyridinyl, 4-pyridinyl, 2-thiazolyl, 4-nitrophenyl, and 2-benzothiazolyl)methanediamines 1a-f with oxalyl chloride in dry dichloroethane in the presence of pyridine affords the corresponding 1,3-bis (heteroaryt)-4,5-imidazolidinediones 3a-f in good to excellent yields. The essential role of pyridine in the reaction mixture is described, and reaction details as well as product characterization is discussed.
