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 and the group of the general formula (II), in which R.sub.1 is aryl, alkylaryl and alkyl group with C.sub.1 to C.sub.4 atoms, and n is 0 and 1, and also covers the compounds of the general formula (I), where R is the group of the formula (II), in which R.sub.1 is aryl and alkylaryl 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.sub.1 is benzyl and p-nitrobenzyl group and n is 0, and p-trifluoromethylchlorbenzene (XVI) prepared N-substituted derivatives of N-methyl-3-(p-trifluoromethylphenoxy)-3 -phenylpropylamine (I), where R is the group of the formula (II), in which n and R are the same as in the compound (XV), which by the reaction with chloroformic acid esther (XVII), where R.sub.1 aryl, alkylaryl and alkyl group with C.sub.1 to C.sub.4 atoms, are converted to N-substituted derivatives of N-methyl-3-(p -trifluoromethylphenoxy)-3-phenylpropylamine (I), where R is the group of the formula (II), in which R.sub.1 is the same as in the compound (XVII), and n is 1, from which is prepared the compound of the formula (I), in which R is hydrogen (Fluoxetin), by basic hydrolysis and/or catalytic hydrogenolysis, when R is the group of the formula (II), in which R.sub.1 is benzyl and p-nitrobenzyl group, and n is 0 and 1.
本发明提供了N-取代N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺的制备方法,其具有通式(I),其中R为氢原子和通式(II)中的基团,其中R1为芳基、烷基芳基和碳原子数为C1到C4的烷基,n为0和1,并且还包括通式(I)的化合物,其中R为通式(II)中的基团,其中R1为芳基和烷基芳基基团,n为0和1。根据本发明,通过N-取代N-甲基-3-苯基-3-羟基丙胺(XV)和p-三氟甲基氯苯(XVI)的缩合反应,制备了N-取代N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺(I),其中R为通式(II)中的基团,其中n和R与化合物(XV)中相同,通过与氯甲酸酯(XVII)反应,其中R1为芳基、烷基芳基和碳原子数为C1到C4的烷基,转化为N-取代N-甲基-3-(对三氟甲基苯氧基)-3-苯基丙胺(I),其中R为通式(II)中的基团,其中R1与化合物(XVII)中相同且n为1,从而通过碱性水解和/或催化氢解制备出通式(I)中R为氢原子(Fluoxetin)的化合物,当R为通式(II)中的基团,其中R1为芳基和p-硝基苯基基团,n为0和1。
