Procedure

To a stirred solution of 4-((3-((S)-phenyl((((R)-quinuclidin-3-yloxy)carbonyl)amino)methyl)phenoxy)methyl)benzoic acid (0.300 g, 0.57 mmol) in DMF (2.5 mL) was added di-iso-propylethylamine (0.40 mL, 2.29 mmol) and HATU (0.262 g, 0.69 mmol) and the mixture stirred at RT for 30 minutes. To the resultant solution was added a solution of 3-(1,3-dioxolan-2-yl)propyl piperidine-4-carboxylate hydrochloride (0.241 g, 0.86 mmol) in DMF (1.8 mL). The mixture was stirred at RT for 18 hours. The mixture was diluted with ethyl acetate, washed with 10% aqueous potassium carbonate, brine (×2), dried (magnesium sulfate), filtered and the solvent evaporated at reduced pressure. The residue was used directly in the next step with no further purification.
