300 mg (2.14 mmol) of potassium carbonate are added to a mixture, prepared under argon, of 300 mg (1.43 mmol) of (3R)-quinuclidine-3-carbonyl chloride hydrochloride (Example 5A) and 180 mg (0.71 mmol) of [(4′-aminobiphenyl-4-yl)amino](oxo)acetic acid [CAS Registry No. 100872-66-0] in 11 ml of a 10:1 mixture of dioxane and DMF. After 18 h at 100° C., the reaction mixture is concentrated in vacuo, and the residue is dissolved in water and acetonitrile and purified by preparative HPLC. The concentrated product fractions are mixed with 5 ml of a 2:1 mixture of acetonitrile and 1 N hydrochloric acid and again concentrated. Drying under high vacuum results in 64 mg (20.3% of theory) of the title compound.
