A process for the preparation on N-methyl-aryloxy-propanamine derivatives of the formula (I) and salts thereof. The invention also relates to the preparation and use novel intermediate of the formula (XII). The invention also relates to the process of further conversion of novel intermediate into N-methyl- aryloxy propanamine derivatives and salts thereof. Wherein Q and P independently represents substituted or unsubstituted aryl group such as phenyl, naphthyl, pyridine, furanyl, pyranyl thienyl, and the like optionally substituted aryl by a halogen, a straight chain or branched alkyl group containing 1 to 6 carbon atoms, -O-alkyl group containing straight chain or branched C1-C6 alkyl group, an alkoxy group containing a straight chain or branched alkyl group having 1 to 6 carbon atoms, which comprises demethylation of N,N-dimethyl analogues of compound of formula (IA).
                            一种制备N-甲基-芳氧基-
丙胺基衍
生物(I式)及其盐的方法。本发明还涉及制备和使用新型中间体(XII式)。本发明还涉及将新型中间体进一步转化为N-甲基-芳氧基-
丙胺基衍
生物及其盐的方法。其中,Q和P分别表示取代或未取代的芳基,例如苯基、
萘基、
吡啶基、
呋喃基、
吡喃基、
噻吩基等,这些芳基可以是通过卤素、直链或支链烷基(含1至6个碳原子)、-O-烷基(含直链或支链C1-C6烷基)或烷氧基(含直链或支链烷基,碳原子数为1至6)进行选択性取代的芳基,其中包括对化合物(IA式)的N,N-二甲基类似物进行去甲基化的步骤。
