Reaction Steps

To a solution of allyl 3-(2-oxo-1-phenyl-2-((R)-quinuclidin-3-yloxy)ethyl-amino)benzoate (I4) (1.40 g, 3.33 mmol) in dry THF (45 ml), were added tetrakis-(triphenylphosphine)palladium(0) (1.15 g, 1.00 mmol) and piperidine (0.99 ml, 1.00 mmol) and the reaction mixture was stirred at 60° C. for 1.5 hours. The solvent was removed in vacuo and the crude was purified by flash chromatography (DCM/MeOH=9/1 to MeOH) to obtain (R)-3-(2-oxo-1-phenyl-2-(quinuclidin-3-yloxy)ethylamino)benzoic acid (500 mg, 39.5% yield).
