Versuchsvorschrift

3-(4-[2-(6,11-Dihydrodibenzo[b,e]thiepin-11-yloxy)-ethoxy]-phenyl)-2-ethoxy-propionic acid ethyl ester (example 2) (220 mg, 0.44 mmol) in ethanol (5 mL) was added NaOH 1N (0.9 mL, 0.9 mmol). The mixture was stirred at room temperature for 16 h. The ethanol was evaporated of and pH adjusted with HCl 1N to pH 1. After extraction with dichloromethane the product was purified by chromatography, using dichloromethane/methanol (9:1) as eluent, to give 126 mg (62%) of the title compound: 1H NMR (300 MHz, CDCl3) δ1.15 (t, 3H), 2.85-3.10 (m, 2H), 3.32-3.42 (m, 1H), 3.52-3.65 (m, 1H), 2.85 (t, 2H), 3.95-4.05 (m, 1H), 4.10-4.22 (m, 2H), 4.5-5.1 (bs, 1H), 5.60-5.75 (bs, 1H), 6.82 (d, 2H), 7.05-7.50 (m, 10H).
