Abstract
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.
