The invention provides a method for the preparation of an intermediate for use in synthesizing a lower alkyl phenidate compound of formula (I), wherein each R1 independently represents an optionally substituted aryl, heteroaryl, alkyl, cycloalkyl, alkoxy, aryloxy, acyl, carboxyl, hydroxyl, halogen, amino, nitro, sulfo or sulfhydryl group, R2 represents a hydrogen atom or a lower alkyl group, n represents an integer from 1 to 5 and m represents an integer from 1 to 3 or a pharmaceutically acceptable salt thereof; which method comprises the steps of: (a) flowing a tosylhydrazone compound of formula (IV), wherein R1, n and m are as defined above in relation to the methylphenidate of formula (I), an organic base and an organic solvent into a fluidic network; and (b) reacting the tosylhydrazone compound of formula (IV) and the base in the fluidic network under thermal and/or photochemical conditions to form a transient diazoamide compound of formula (V), wherein R1, n and m are as defined above in relation to the methylphenidate of formula (I).
该发明提供了一种制备用于合成化合物的中间体的方法,该化合物是具有如下式(I)的较低烷基苯二酸酯化合物,其中每个R1都独立地代表一个可选择取代的芳基、杂环芳基、烷基、环烷基、烷氧基、芳氧基、酰基、羧基、羟基、卤素、氨基、硝基、磺酰基或硫氢基,R2代表氢原子或较低烷基基团,n表示1到5的整数,m表示1到3的整数或其药用可接受的盐;所述方法包括以下步骤:(a)将如下式(IV)中定义的R1、n和m与上述关于如下式(I)的甲基苯二酸酯相关的甲磺酰腙化合物、有机碱和有机溶剂导入到流体网络中;以及(b)在热和/或光化学条件下在流体网络中将如下式(IV)中定义的甲磺酰腙化合物和碱反应以形成如下式(V)的瞬时重氮酰胺化合物,其中R1、n和m如上述关于如下式(I)的甲基苯二酸酯相关的定义。
