Reaction Steps

10 ml of N,N-dimethylformamide was added to a mixture of 1.2 g of 6-methyl-2-(2-phenylethyl)pyridyl trifluoromethane sulfonate, 522 mg of 3-ethynyl-3-quinuclidinol, 400 mg of tetrakis(triphenylphosphine)palladium(0), 217 mg of cuprous iodide and 1.7 ml of triethylamine, followed by heating under stirring at 50° C. in an oil bath for one hour in a nitrogen atmosphere. After cooling as it was, the reaction solution was sprinkled over silica gel and subjected to silica gel column chromatography using chloroform/methanol/aqueous 36% ammonia (46:5:0.5) as an eluent for separation and purification, to give 490 mg of the target compound.
