Procedure

A mixture of 720 mg of 2-benzyl-3-bromo-6-(2-methoxyethyloxy)pyridine, 340 mg of 3-ethynyl-3-quinuclidinol, 130 mg of tetrakis(triphenylphosphine)palladium(0), 42 mg of cuprous iodide, 0.93 ml of triethylamine and 3 ml of N,N-dimethylformamide was heated under stirring in an oil bath kept at 80° C. for 2 hours in a nitrogen atmosphere. After cooling as it was, the mixture was extracted with ethyl acetate-dilute aqueous ammonia. The organic phase was washed with water and brine, dried over anhydrous magnesium sulfate and evaporated. The residue was subjected to NH-silica gel column chromatography and eluted with 20-100% ethyl acetate/hexane and then with 2.5% methanol/ethyl acetate, to give 500 mg of the target compound.
