  The invention relates to a method for producing an addition salt of 2,4′-dimethyl-3-piperidino-propiophenone (tolperisone) with a pharmaceutically acceptable acid, of formula (I). According to the invention, 4-methylpropiophenone is reacted with piperidine hydrochloride and 1,2-dioxolane in the presence of an acid serving as a catalyst, and the tolperisone obtained in the form of an acid addition salt is separated by filtering after the reaction mixture has cooled down.

  本发明涉及一种制备2,4'-二甲基-3-哌嗪基丙酮酸加成盐（托尔哌酮）的药物可接受酸的方法，其化学式为（I）。根据本发明，将4-甲基丙酮酸与盐酸哌啶和1,2-二氧兰在催化剂作用下反应，反应混合物冷却后通过过滤分离得到托尔哌酮的酸加成盐。

  The invention relates to a method for producing highly pure 2,4′-dimethyl-3-piperidino-propiophenone (tolperisone) (formula I) and the pharmaceutically acceptable salts, hydrochlorides, and hydrates thereof. The method allows the content of the undesired byproduct 2-methyl-1-(4-methylphenyl) propenone (4-MMPPO) to be kept significantly lower than in previously known methods. The invention further relates to active substance formulations which contain tolperisone and are suitable, among other things, for producing combination preparations used for treating patients suffering from Alzheimer's disease. The invention also relates to topical formulations, controlled release (CR) formulations, and transdermal therapeutic systems, such as active substance patches, which contain less than 50 ppm, preferably less than 10 ppm, more preferably less than 7 ppm, and most preferably less than 3 ppm or 0 ppm (i.e. less than the detectable amount) of the undesired byproduct 2-methyl-1-(4-methylphenyl) propenone (4-MMPPO) in relation to 100 percent by weight of active substance.
