2,3-Dihydroxybutanedioic Acid → (S)-N,N-dimethyl-3-(naphthyloxy)-3-(2-thienyl)propylamine D-tartrate

Participants

Reaction Steps

first by converting it to a mixture of diastereoisomeric salts of N,N-dimethyl-3-(naphthyloxy)-3-(2-thienyl)propylamine/D-tartrate via reaction with optically active tartaric acid in the molar ratio 1:2 relative to the substance of formula III or with optically active alkali metal tartrate or ammonium tartrate, or an alkylammonium tartrate, of formula IV, in the molar ratio 1:1, followed by isolating the salt (S)—N,N-dimethyl-3-(naphthyloxy)-3-(2-thienyl)propylamine/D-tartrate (2:1) (Scheme 2) from the mixture of the diastereoisomeric salts in an organic solvent, water or a mixture thereof
