A process for the preparation of venlafaxin and/or the physiologically acceptable addition salts thereof that consists of reacting a compound of general formula (II) where R is a C1-C10 alkyl, aryl, aralkyl or cycloalkyl group of 3 to 6 atoms of carbon, with a organomagnesium compound of general formula (III) where X is an atom of halogen and, if desired, a salt of the thus obtained venlafaxin is formed by reaction thereof with a physiologically acceptable acid.
一种制备文拉法辛和/或其生理学上可接受的加成盐的工艺,包括将通式(II)的化合物(其中R为3至6个碳原子的C1-C10烷基、芳基、芳烷基或环烷基)与通式(III)的有机镁化合物(其中X为卤素原子)反应,如果需要,将由此获得的文拉法辛与生理学上可接受的酸反应生成盐。
