Procedure

To a stirred solution of 3-(1,3-dioxolan-2-yl)benzyl 4-((3-((S)-phenyl((((R)-quinuclidin-3-yloxy)carbonyl)amino)methyl)phenoxy)methyl)benzoate (0.32 g, 0.57 mmol) in THF (8 mL) was added 2M aqueous hydrochloric acid (8 mL). The reaction mixture was stirred at RT for 1 hour. The mixture was diluted with ethyl acetate and was washed sequentially with saturated aqueous sodium hydrogen carbonate and brine. The organic extract was dried (magnesium sulfate), filtered and the solvent evaporated at reduced pressure. The residue was used in the next step with no further purification.
