Versuchsvorschrift

To a stirred solution of 3-[7-(1,3-dimethyl-1H-pyrazol-5-yl)-1,2,4,5-tetrahydro-3H-3-benzazepin-3-yl]-1-butanol (0.25 g) (intermediate 9) in chloroform (8 ml), at room temperature, thionyl chloride (0.11 ml) was added dropwise. After 2h, saturated aqueous sodium hydrogencarbonate (5 ml) was added, the reaction mixture was extracted with dichloromethane (15 ml), the organic phase dried with sodium sulphate and the solvent evaporated under reduced pressure. The crude product was purified by chromatography on silica gel with 80% cyclohexane-ethyl acetate to give the title compound (0.23 g) as a white solid.
