Conjugate addition reaction of various nucleophiles across the vinyl group of 2-chloro-4-vinylpyrimidine, 2-chloro-4-(1-phenylvinyl)pyrimidine and 2-chloro-4-vinyl-quinazoline provides the corresponding 2-chloro-4-(2-substituted ethyl)pyrimidines and 2-chloro-4-(2-substituted ethyl)quinazolines. Treatment of these products, without isolation, with N-methylpiperazine results in nucleophilic displacement
各种亲核试剂在 2-chloro-4-vinylpyrimidine、2-chloro-4-(1-phenylvinyl)pyrimidine 和 2-chloro-4-vinyl-quinazoline 的乙烯基上的共轭加成反应提供了相应的 2-chloro-4- (2-取代乙基)嘧啶和2-氯-4-(2-取代乙基)喹唑啉。未经分离,用 N-甲基哌嗪处理这些产物会导致氯化物的亲核置换并产生相应的 2,4-二取代嘧啶和喹唑啉。
