The present solution relates to a method comprising, as a key step, production of optically pure or optically enriched tapentadol of formula I, in which optically pure or optically enriched (2R,3R)-amines of general formula V, wherein R stands for a phenylmethyl group, substituted or non-substituted in the benzene ring, e.g. benzyl or 4-methoxybenzyl, benzhydryl or trityl group, are hydrogenated on a metal catalyst and, if desired, the obtained tapentadol is converted by the action of pharmaceutically acceptable acids to respective salts, such as to hydrochloride.
本发明涉及一种方法,其关键步骤是制备公式I的光学纯或光学富集的tapentadol,其中光学纯或光学富集的(2R,3R)-胺的普通公式V,其中R代表苯甲基基团,在苯环中被取代或未取代,例如苄基或4-甲氧基苄基,苯甲基或三苯甲基基团,在
金属催化剂上进行氢化,并且如果需要,所得到的tapentadol可通过药用酸的作用转化为相应的盐,例如盐酸盐。
