A series of new 6-piperazinyl-3,4-dihydroquinazolin-2(1H)-ones have been synthesized. The compounds are structurally related to adoprazine, a potential atypical antipsychotics bearing potent D

receptor agonist properties. Buchwald-Hartwig coupling of suitably modified aryl bromides with tert-butyl piperazine-1-carboxylate afforded the advanced intermediate piperazinyl-3,4-dihydroquinazolin-2(1H)-one. The reductive amination of the latter with appropriately designed biarylaldehydes accomplished the synthesis of these compounds.
已合成一系列新的6-哌嗪基-3,4-二氢喹唑啉-2(1H)-酮。这些化合物在结构上与阿多普拉辛(adoprazine)相关,后者是一种潜在的非典型抗精神病药物,具有强效的D2受体拮抗剂和5-HT1A受体激动剂性质。通过适当改性的芳基溴化物与叔丁基哌嗪-1-羧酸酯的Buchwald-Hartwig偶联反应,得到了先进的中间体哌嗪基-3,4-二氢喹唑啉-2(1H)-酮。后者与设计合理的双芳基醛进行还原胺化反应,完成了这些化合物的合成。
