Procedure
50 ml of N,N-dimethylformamide was added to a mixture of 2.0 g of 3-benzyl-5-methoxycarbonyl-2-pyridyl trifluoromethanesulfonate, 742 mg of 3-ethynyl-3-quinuclidinol, 1.5 g of tetrakis(triphenylphosphine)palladium(0), 374 mg of cuprous iodide and 2.7 ml of triethylamine, followed by heating under stirring for one hour in an oil bath kept at 60° C. in a nitrogen atmosphere. After cooling as it was, ethyl acetate and aqueous ammonia were added thereto and the mixture was extracted with ethyl acetate. The organic phase was further washed with brine, dried over anhydrous magnesium sulfate and the solvent was removed. The residue was subjected to silica gel column chromatography using chloroform/methanol/aqueous 36% ammonia (46:3:0.3) as an eluent for separation and purification, to give 1.1 g of the target compound.
