咪唑和1,2,4-三嗪之间的分子内逆电子需求的Diels-Alder反应由三亚甲基系链从咪唑N1位置连接到三嗪C3,从而以极好的收率进行生产1,2,3,4-四氢-1,5-萘啶。该反应通过环加成反应进行,随后损失氮气,然后逐步损失腈。使用四亚甲基系链的类似分子内环加成反应也以可接受的收率得到了2,3,4,5-四氢-1 H-吡啶并[3,2- b ]氮杂。微波辐射也可以促进产生四氢-1,5-萘啶的反应。

4-substituted pyridine or a 1-substituted imidazole ring and the carboxamide nitrogen atom showed the best combination of potencies in the two assays. Several of these compounds were found to be orallyactive inhibitors of LTE4-induced bronchoconstriction in the guinea pig and LTE4-induced skin wheal formation in the rat. One of the most potent analogues, 2-(1-methyl-ethyl)-N-(1H-imidazol-1-ylbutyl)-11-oxo-11H-pyrido
