A series of new dihydropyridines, butanamide, dihydropyridazines and thiourea derivatives have been prepared through the reactions of 3‐aminopyridine (1) and N‐(pyridin‐3‐yl)‐3‐(pyridin‐3‐ylimino)butanamide 3 with some electrophilic reagents, aryl diazonium salts and isothiocyanates. Elementary analysis, MS, IR, and 1H NMR spectra confirmed the identity of the products.
通过3-氨基吡啶(1)和N-(吡啶-3-基)-3-(吡啶-3-氨基)丁酰胺3与一些亲电子的反应,制备了一系列新的二氢吡啶,丁酰胺,二氢哒嗪和硫脲衍生物。试剂,芳基重氮盐和异硫氰酸盐。元素分析,MS,IR和1 H NMR光谱证实了产物的身份。
