Procedure
(RS)-N,N-dimethyl-3-(naphthyloxy)-3-(2-thienyl)propylamine/D-tartrate (773 g, 1 mole) is dissolved in warm tetrahydrofuran (1500 ml) with addition of water (40 ml). After cooling down to ambient temperature, the mixture is stirred for 24 h. The precipitated crystals are recrystallized once more in tetrahydrofuran (400 ml) with an addition of water (12 ml) following the same procedure. Yield: 170 g (22%). Optical purity: 99.5% ee (CE).
