Hydroxyzine and aripiprazole are active pharmaceutical ingredients that have been largely acknowledged for their antipsychotic properties. Deuterium labeled isotopes of hydroxyzine and aripiprazole are internal standards that can aid in the further research of non-isotopic forms via quantification analysis using HPLC-MS/MS. The synthesis of hydroxyzine-d8 was accomplished by coupling piperazine-d8 with 4-chlorobenzhydryl chloride followed by the reaction of the first intermediate with 2-(2-chloroethoxy) ethanol to afford 11.7% of hydroxyzine-d8 with 99.5% purity. The synthesis of aripiprazole-d8 was also achieved in two steps. 1,4-Dibromobutane-d8 reacted with 7-hydroxy-3,4-dihydro-2(1H)-quinolinone. The first intermediate was then coupled with 1-(2, 3-dichlorophenyl)piperazine hydrochloride to produce 33.4% of aripiprazole-d8 with 99.93% purity.
羟嗪和阿立哌唑是被广泛认可的活性药物成分,具有抗精神病特性。氘标记的羟嗪和阿立哌唑同位素作为内标,可以通过高效液相色谱-质谱/质谱 (HPLC-MS/MS) 定量分析,帮助进一步研究非同位素形式。
羟嗪-d8 的合成是通过将氘标记的哌嗪与 4-氯苯甲基氯偶联而实现的,随后第一个中间体与 2-(2-氯乙氧基)乙醇反应,最终得到 11.7% 的羟嗪-d8,纯度为 99.5%。阿立哌唑-d8 的合成同样通过两个步骤完成。1,4-二溴丁烷-d8 与 7-羟基-3,4-二氢-2(1H)-喹啉酮反应。然后,第一个中间体与 1-(2, 3-二氯苯基)哌嗪盐酸盐偶联,最终生成 33.4% 的阿立哌唑-d8,纯度为 99.93%。
