The synthesis of 7-hydroxy, 8-hydroxy and 7,8-dihydroxy prochlorperazines (3a) and per-phenazines (3b) is reported. The parent ehlorophenothiazines were prepared analogously to previously reported chlorpromazine (3e) metabolite syntheses. The prochlorperazine side chain was introduced in one step using 1-(3-chloropropyl)-4-methylpiperazine and the perphenazine side chain in two steps, first reaction
报道了7-羟基,8-羟基和7,8-二羟基丙氯嗪(3a)和过吩嗪(3b)的合成。与先前报道的氯丙嗪(3e)代谢产物合成类似地制备母体埃洛洛吩噻嗪。使用1-(3-氯丙基)-4-甲基哌嗪和二氮杂吩嗪侧链分两步引入氯丙嗪侧链,首先与1-溴-3-氯丙烷反应,然后与1-哌嗪乙醇反应。在温和条件下,使用甲醇氯化氢除去甲氧基亚甲氧基的O-保护基。还报道了7-羟基去甲基丙氯嗪和7-羟基氯丙嗪季甲基碘的制备。
