It is provided a process for the preparation of aripiprazole lauroxil that comprises reacting 1-(hydroxymethyl) aripiprazole with lauric acid in the presence of a suitable solvent and a carboxyl activating agent in the presence of a suitable solventand, optionally,in the presence of an appropriate base. -(Hydroxymethyl) aripiprazole can be prepared by reacting aripiprazol or an hydrate thereof with paraformaldehyde in the presence of a suitable organic 10 solvent and a suitable base, wherein the reaction is carried out without the addition of water as a solvent to the reaction mixture.Additionally, (7-(4-(4- (2,3-dichlorophenyl)piperazin-1-yl)butoxy)-3,4-dihydro-2-oxoquinolin-1(2H)- yl)methyl formate is provided as a reference standard.
提供了一种制备阿立哌唑酯洛西尔的过程,包括在适当溶剂和羧基活化剂的存在下,将1-(羟甲基)阿立哌唑与月桂酸反应,可选地,在适当碱的存在下进行。可以通过将阿立哌唑或其水合物与多聚甲醛在适当有机溶剂和适当碱的存在下反应来制备(羟甲基)阿立哌唑,其中该反应在不向反应混合物中添加水作为溶剂的情况下进行。此外,还提供了(7-(4-(4-(2,3-二氯苯基)哌嗪-1-基)丁氧基)-3,4-二氢-2-氧喹啉-1(2H)-基)甲酸甲酯作为参考标准。
