The invention relates to a process for the preparation of risperidone (chemical name: 3-[2-[4-(6-fluoro-l,2-benzisoxazole-3-yl)-1piperidmyl]ethyl-2-methyl-6,7,8,9-terahydro-4H--pyrido[l,2-a]pyrimidine-4-one) of the formula (I) by reacting 3-(2-chloroethyl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[l,2-a]pyrimidine-4-one of the formula (II) and 6-fluoro-3-(4-piperidinyl)-l,2-benzisoxazole of the formula (III), in which the reaction is carried out in dry methanol solvent under pressure, at a temperature between 65 and 90 °C, the product is recovered by using a methanol/water mixture of specified ratio and if desired is recrystallized from an alcohol.
该发明涉及一种制备利培酮(化学名称:3-[2-[4-(6-氟-1,2-苯并异噁唑-3-基)-1-哌啶基]乙基-2-甲基-6,7,8,9-四氢-4H-吡啶[1,2-a]嘧啶-4-酮)的过程,通过将式(II)的3-(2-氯乙基)-2-甲基-6,7,8,9-四氢-4H-吡啶[1,2-a]嘧啶-4-酮和式(III)的6-氟-3-(4-哌啶基)-1,2-苯并异噁唑反应得到,其中反应在干燥的甲醇溶剂中在压力下进行,在65至90°C的温度下进行,通过使用规定比例的甲醇/水混合物回收产物,如有需要,可从醇中再结晶。
