Benzyl cyanide reacts with triethylorthoformate and piperidine in DMF solution to yield the title compound 2. This reacted with aromatic amines to yield either aminoacrylonitriles or quinoline depending on reaction conditions and substitution pattern on the aromatic amine. The reaction of compound 2 with hydrazine hydrate could only be effected in the microwave oven and resulted in the formation of
苄基氰化物在DMF溶液中与原甲酸三乙酯和哌啶反应生成标题化合物2。根据芳族胺的反应条件和取代方式,它与芳族胺反应生成氨基丙烯腈或喹啉。化合物2与水合肼的反应只能在微波炉中进行,导致氨基吡唑7的形成。7的重氮化并与活性亚甲基试剂偶合,得到吡唑并[5,1- c ]-[1,2,4]三嗪衍生物。
