The invention provides the preparation procedure for N-substituted derivatives of N-methyl-3-(p-trifluoromethylphenoxy)-3-phenylpropylamine having the general formula (I), where R is hydrogen, benzyl and p-nitrobenzyl group, and n is 0, and where R is aryl, alkylaril and alkyl group with C₁ to C₄ atoms, and n is 1, and also covers the compounds of the general formula (I), where R is aryl and alkylaril group, and n is 0 and 1.
According to this invention by condensation of N-substituted derivatives of N-methyl-3-phenyl-3-hydroxypropylamine (XV), where R is benzyl and p-nitrobenzyl group and n is 0, and p-trifluoromethylchlorbenzene (XVI) prepared are N-substituted derivatives of N-methyl-3-(p-trifluoromethylphenoxy)-3-phenylpropylamine (I), where n and R are the same as in the compound (XV), which by the reaction with chloroformic acid esther (XVII), where R is aryl, alkylaril and alkyl group with C₁ to C₄ atoms, are converted to N-substituted derivatives of N-methyl-3-(p-trifluoromethylphenoxy)-3-phenylpropylamine (I), where R is the same as in the compound (XVII), and n is 1, from which N-methyl-3-(p-trifluoromethylphenoxy)-3-phenylpropylamine (I) is prepared by basic hydrolysis and/or catalytic hydrogenolysis, when R is benzyl and p-nitrobenzyl group, and n is 0 and 1.
本发明提供了具有通式(I)的N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺的N-取代衍生物的制备步骤,其中R为氢、苄基和对硝基苄基、且 n 为 0,以及 R 为芳基、烷基芳烷基和具有 C₁ 至 C₄ 原子的烷基且 n 为 1 的通式(I)化合物,还包括 R 为芳基和烷基芳烷基且 n 为 0 和 1 的通式(I)化合物。
根据本发明,通过缩合 N-甲基-3-苯基-3-羟基丙胺的 N-取代衍生物 (XV),其中 R 为苄基和对硝基苄基,n 为 0、和对三氟甲基氯苯(XVI)制备的是 N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺(I)的 N-取代衍生物,其中 n 和 R 与化合物(XV)中的相同,通过与氯仿酸酯(XVII)反应、其中 R 为芳基、烷基芳基和具有 C₁ 至 C₄ 原子的烷基,通过与氯甲酸酯 (XVII) 反应,转化为 N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺 (I) 的 N-取代衍生物,其中 R 与化合物 (XVII) 中的相同、当 R 为苄基和对硝基苄基,且 n 为 0 和 1 时,N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺(I)由其通过碱性水解和/或催化氢化裂解制备。
