An improved process for the preparation of aripiprazole (1) which comprises (i) reacting 6-hydroxy-l-indanone (11) with 1,4-dihalobutane (12) in the presence of a base and a solvent at a temperature in the range of 90 to 110 deg C to form the novel intermediate 6-(4-halo butoxy)-indan-1-one (3), (ii) reacting the novel intermediate with 1-(2,3-clichlorophenyl)-piperazine (9) to get another novel intermediate 6-[4-[4-(2,3-dichlorophenyl)-l-piperazinyl]butoxy]-indan-l-one (2) and (iii) reacting the resulting novel compound with sodium azide. The invention also relates to the novel intermediates of the formulae (2) & (3) and processes for their preparation. The invention also includes intermediate compounds useful for the preparation of aripiprazole.
一种改进的阿立哌唑(1)制备工艺,包括(i)在碱和溶剂存在下,将6-羟基-1-茚酮(11)与1,4-二卤丁烷(12)在90至110℃的温度范围内反应,形成新的中间体6-(4-卤丁氧基)-茚-1-酮(3),(ii)将新的中间体与1-(2,3-二氯苯基)-哌嗪(9)反应,得到另一个新的中间体6- [4- [4-(2,3-二氯苯基)-1-哌嗪基]丁氧基]茚-1-酮(2),以及(iii)将所得的新化合物与偏氮化钠反应。本发明还涉及公式(2)和(3)的新中间体及其制备工艺。本发明还包括用于制备阿立哌唑的中间化合物。
