Versuchsvorschrift

The (S)—N,N-dimethyl-3-(1-naphthalenyloxy)-3-(2-thienyl)propanamine di-p-anisoyl-L-tartarate salt (9a) (100 gm) was added to biphasic solvent mixture of water (500 ml) and dichloromethane (250 ml). To the slurry aqueous ammonia was added to adjust the pH to 10.8 and stirred further for 15-30 minutes. Organic layer was separated, washed with water, brine and concentrated to get thick oily mass of (S)-(+)-N,N-dimethyl-3-(1-naphthalenyloxy)-3-(2-thienyl)propanamine (6a). Yield: 44 gm.
