Abstract

Process for the preparation of N-methyl-3-phenyl-(p- trifluoromethylphenoxy)propylamine Comprises the following stages: a) reacting the ethyl 3- phenyl-3-hydroxypropionate with methylamine to yield N-methyl-3-phenyl-3-hydroxypropanamide, b) reducing this compound with lithium aluminium hydride to yield N-methyl-3-phenyl-3-hydroxypropylamine, c) reacting approximately equimolar quantities of the above product, sodium hydride and 1-chloro-4-(trifluoromethyl) benzene in dimethylacetamide to form the title product I, and d) optionally converting the product I so formed into its hydrochloride by the addition of hydrogen chloride. The starting ethyl 3-phenyl-3-hydroxypropionate is obtained by condensation between benzaldehyde and ethyl acetate in the presence of a strong base, preferably lithium bistrimethylsilylamide. The invention is of use in the industrially advantageous preparation of I.
