6,6'-(5,6-diethyl-1,2,4-triaz. in-3-yl)-2,2'-bipyridine was synthesized by a two-step reaction. The reaction time of the first step was shortened from 17d to 3d by improving reaction conditions. The structures of intermediate and target products were characterized by elemental analysis, IR, 1 HNMR and MS. In addition,The reaction mechanism was studied.%以6,6'-二氰-2,2'-联吡啶为原料,经两步反应,合成了6,6'二(5,6二乙基-1,2,4-三嗪-3-基)-2,2'-联吡啶.第一步改变条件使反应时间由17d缩短到3d,得到的中间体和目标产物经元素分析、IR,1 HNMR和MS等表征确认.此外,对反应机理进行了初步探讨.
