Versuchsvorschrift
The polar diastereoisomer of (4-dimethylamino-4-phenylcyclohexyl)-carbamic acid phenyl ester (338 mg, 1 mmole) was added to a solution of 5-fluoro-3-piperidine-3-yl-1H-indole (218 mg, 1 mmole) in dioxane (10 ml). The reaction mixture was then boiled under reflux for 32 hours. The reaction mixture was worked up by distilling off dioxane and diluting with water (10 ml). The reaction mixture was adjusted to pH 11 with 5M NaOH and extracted with EE (3×15 ml). The organic phase was dried with Na2SO4 and concentrated by evaporation. The polar diastereoisomer of 3-(5-fluoro-1H-indol-3-yl)piperidine-1-carboxylic acid-(4-dimethylamino-4-phenylcyclohexyl)-amide was purified by column chromatography [silica gel 60 (25 g); methanol (250 ml)]. It was obtained as a colourless solid in a yield of 200 mg (43%).
