Abstract

New process for the enantiospecific preparation of (S)-2-ethylamino-1-(3-trifluoromethylphenyl)propane, characterised in that benzaldehyde is condensed with (S)-alaninol and that, after reduction, the product originating from the reaction is condensed with acetaldehyde to obtain (S)-N-benzyl-N-ethyl alaninol, which is subjected to the action of thionyl chloride to give, after neutralisation, (S)-2-(N-benzyl-N-ethylamino)-1-chloropropane, which is in its turn condensed with 3-trifluoromethylphenylmagnesium bromide to give (S)-2-(N-benzyl-N-ethylamino)-1-(3-trifluoromethylphenyl)- propane which, after debenzylation by hydrogenolysis, produces (S)-2-ethylamino-1-(3-trifluoromethylphenyl)propane.
