실험 절차

tBuOK (16.8 g), and 18-crown-6 (0.25 g) are added to a solution of (S)-N,N-dimethyl-3-(naphthyloxy)-3-(2-thienyl)propylamine (31 g) in sulfolane (100 ml), bubbled with a moderate stream of nitrogen, and the mixture is stirred and heated at 110° C. for 2 hours. After cooling down to lab temperature, the mixture is diluted with water (300 ml) and the racemic product is extracted with toluene. After evaporation, 25 g (81%) of RS)-N-methyl-3-(naphthyloxy)-3-(2-thienyl)propylamine is obtained.
