Procedure

45.4 mg (0.30 mmol) of 3-methoxyphenyl isocyanate and 84.8 μl (0.61 mmol) of triethylamine are added to a solution of 60 mg (0.15 mmol) of ((3R)—N-(4′-aminobiphenyl-4-yl)quinuclidine-3-carboxamide dihydrochloride (Example 7A) in 0.5 ml of DMF. After 18 h at room temperature, 5 ml of water are added to the reaction mixture. The resulting precipitate is filtered off with suction, washed with water and dried under high vacuum. A preparative HPLC is carried out for further purification. The product fractions are concentrated, mixed with 3 ml of 1 N hydrochloric acid, again concentrated and dried under high vacuum. 22 mg (27.6% of theory) of the title compound are obtained.
