2-Alkoxy(aralkoxy)-5-chloro[1,2,4]triazolo[1,5-a]quinazolines have been synthesized. The corresponding 2-alkoxy(aralkoxy)[1,2,4]triazolo[1,5-a]quinazolin-5-ones were chlorinated with either oxalyl chloride or phosphorus oxychloride. The chlorine atom at 5-position of the targeted [1,2,4]triazolo[1,5-a]quinazolines was replaced with multifunctional N-nucleophiles. This provided the preparation of the
合成了2-烷氧基(芳烷氧基)-5-氯[1,2,4]三唑并[1,5-a]喹唑啉。相应的 2-烷氧基(芳烷氧基)[1,2,4]三唑并[1,5-a]喹唑啉-5-酮用草酰氯或磷酰氯进行氯化。目标[1,2,4]三唑并[1,5-a]喹唑啉的5位氯原子被多功能N-亲核试剂取代。这提供了在 5 位带有多种取代基的杂环体系的制备。
