The title compound was prepared by a simple route involving Eschenmoser sulfide contraction between 3-(3-bromo-2-oxopropyl)quinazolin-4(3H)-one (11) and piperidine-2-thione (13) followed by chemoselective catalytic hydrogenation. This short but flexible procedure also permitted access to N-alkyl analogues, and to analogues in which the piperidine ring was replaced by other saturated nitrogen-containing
标题化合物通过简单的路线制备,包括 3-(3-bromo-2-oxopropyl)quinazolin-4(3H)-one (11) 和哌啶-2-硫酮 (13) 之间的 Eschenmoser 硫化物收缩,然后进行化学选择性催化氢化. 这种简短但灵活的程序还允许获得 N-烷基类似物,以及其中哌啶环被其他饱和含氮杂环取代的类似物。
