Abstract A simple and efficient process for the large-scale preparation of agomelatine (1), an antidepressant drug is, described. Agomelatine was prepared in a linear manner starting from readily available, inexpensive 2-naphthol. Key steps in the synthesis are Friedel–Crafts acylation of 2-naphthyl acetate with chloroacetyl chloride, reduction of keto intermediate, and nucleophilic displacement of
摘要 描述了一种简单有效的大规模制备抗抑郁药阿戈美拉汀 (1) 的方法。阿戈美拉汀是从容易获得的廉价 2-萘酚开始以线性方式制备的。合成的关键步骤是 2-萘基乙酸酯与氯乙酰氯的 Friedel-Crafts 酰化、酮中间体的还原以及氯中间体与二甲酰胺钠的亲核置换。描述了一种系统方法,通过控制杂质将过程简化为强大的可扩展过程。图形概要
