Procedure

5-(3-Chloropropyl)-10,11-dihydro-5H-dibenzo[b,f]azepine (1.70 g, 6.25 mmol, prepared as described in example 1), and quinuclidine-3-carboxylic acid methyl ester (0.85 g, 5.0 mmol) were dissolved in 2-butanone (25 ml). Dry potassium carbonate (4.15 g, 30 mmol) and sodium iodide (0.75 g, 5 mmol) were added and the stirred mixture was heated at reflux temperature for 5 h. After cooling to room temperature, toluene (25 ml) and water (25 ml) were added. An oily precipitate was formed, which was separated from the solvents by decanting and dissolved in dichloromethane (30 ml). The solution was washed with water (2×30 ml), 1 N hydrochloric acid (2×30 ml), saturated sodium hydrogencarbonate solution (30 ml) and water (30 ml). The organic layer was dried over MgSO4Evaporation in vacuo afforded 1.15 g 1-(3-(10,11-dihydro-5H-dibenz[b,f]azepin-5-yl)-1-propyl)-3-methoxycarbonyl-quinuclidinium hydroxide. The crude product was directly used in the next step without further purification.
