ABSTRACT Herein, we report an ultrasonic promoted facile and convenient “one-pot” procedure for the synthesis of new [1,2,4]triazolo[1,5-a]pyridine derivatives 3, 4 and 5, using Amberlite IRA-400, in short reaction times and high yields and its comparison with classical reaction conditions. The structures of new compounds were assigned with the help of analytical 1H, 13C NMR, and mass spectral studies
摘要 在此,我们报告了一种使用 Amberlite IRA-400 合成新的 [1,2,4] 三唑并 [1,5-a] 吡啶衍生物 3、4 和 5 的超声波促进的简便“一锅”程序,反应时间短,收率高,并与经典反应条件进行比较。新化合物的结构是在分析 1H、13C NMR 和质谱研究的帮助下确定的。图形概要
