A solution of methyl 1-[4-[[3-[(N-[(3R)-quinuclidin-3-yl]oxycarbonylanilino)methyl]phenoxy]methyl]benzoyl]azetidine-3-carboxylate (Intermediate 7 above described) (190 mg, 0.32 mmol) in THF (3 mL) and methanol (3 mL) was added with an aqueous solution of 1N lithium hydroxide (0.64 mL, 0.64 mmol). The reaction was stirred at room temperature for 18 hours. The mixture was cooled to 0° C. and acidified by addition of 2N hydrochloric acid dropwise to pH≈2-3. The mixture was allowed to warm to room temperature and the solvent removed in vacuo and azeotroped with toluene to dryness. The crude material was redissolved in dimethylformamide (3 mL). (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (161 mg, 0.38 mmol), 4-(dimethylamino)pyridine (20 mg, 0.16 mmol) followed by N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (123 mg, 0.64 mmol) were added, and reaction mixture was stirred at room temperature for 18 hours. The solvent was removed in vacuo and the residue was partitioned between EtOAc (50 mL) and water (50 mL) The organic phase was dried over MgSO4, filtered and the solvent was removed in vacuo. The residue was purified twice by preparative HPLC to yield the title compound as white solid (40 mg, 13% yield over two steps).
