実験手順

64.3 mg (0.46 mmol) of potassium carbonate are added to a mixture, prepared under argon, of 65.1 mg (0.31 mmol) of (3R)-quinuclidine-3-carbonyl chloride hydrochloride (Example 5A) and 45.0 mg (0.15 mmol) of 4′-amino-N-isopropylbiphenyl-4-sulfonamide (Example 12A) in 2.2 ml of a 10:1 mixture of dioxane and DMF. After 18 h at 100° C., the reaction mixture is concentrated in vacuo. The residue is dissolved in water and acetonitrile and purified by preparative HPLC. The product fractions are concentrated, mixed with 5 ml of a 2:1 mixture of acetonitrile and 1 N hydrochloric acid, again concentrated and dried under high vacuum. 21 mg (29.2% of theory) of the title compound are obtained. HPLC (Method 1): Rt=3.93 min. MS (ESIpos): m/z=428 (M+H)+.
