Procedure

A solution of 50 mg (0.13 mmol) of ((3R)—N-(4′-aminobiphenyl-4-yl)quinuclidine-3-carboxamide dihydrochloride (Example 7A) and 38.5 μl (0.32 mmol) of cyclopentanecarbonyl chloride in 1.0 ml of pyridine is stirred at room temperature for 18 h. The reaction mixture is mixed with 3 ml of DMSO and purified by preparative HPLC. The product fractions are concentrated, mixed with 5 ml of 1 N hydrochloric acid, again concentrated and dried under high vacuum. 22 mg (38.2% of theory) of the title compound are obtained.
