실험 절차

A mixture of 2-ethyl-6-fluoro-3-piperidin-4-yl-1H-indole (0.9 g), 1-(3-Bromo-propylsulfanyl)-4-fluoro-benzene (1.0 g), potassium iodide (20 mg) and potassium carbonate (0.7 g) in DMF (10 ml) is heated at 100° C. for 3 h, and allowed to cool to rt overnight. Ethyl acetate (50 ml) and water (25 ml) are added and the organic phase is washed with water, dried and concentrated in vacuo. The crude product is purified by flash chromatography (95:5 CH2Cl2:MeOH) and its hydrochloride salt is prepared by reaction in acetone with the appropriate amount of ethereal HCl giving, after recrystallisation from ether, 1.1 g pure product (70%) as white crystals.
