Novel 9,9-dimethyl-8,12-dihydro-9H-chromeno[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-11(10H)-one derivatives were synthesised by the reactions of triethyl orthoformate or aromatic aldehydes with chromeno[2,3-d]pyrimidine derivatives, which were prepared by the reactions of hydrazine monohydrate and formimidate derivatives. Formimidate were synthesised by the reactions of 2-amino-7,7-dimethyl-5-oxo-4-aryl-5
9,9-二甲基-8,12-二氢-9H-色基[3,2-e][1,2,4]三唑并[1,5-c]嘧啶-11(10H)-one衍生物的合成原甲酸三乙酯或芳香醛与色诺[2,3-d]嘧啶衍生物的反应,其由一水合肼和甲酰亚胺衍生物反应制备。通过 2-氨基-7,7-二甲基-5-氧代-4-芳基-5,6,7,8-四氢-4H-色烯-3-腈衍生物和原甲酸三乙酯的反应合成甲酰亚胺。12-(4-甲氧基苯基)-9,9-二甲基-8,12-二氢-9H-色基[3,2-e][1,2,4]三唑并[1,5-c]嘧啶- 11(10H)-one是通过单晶X射线衍射分析确定的。
