Procedure

A mixture of 110 mg of 4-benzyl-5-bromo-2-(3-pyridyl)pyrimidine, 59 mg of 3-ethynyl-3-quinuclidinol, 19 mg of tetrakis(triphenylphosphine)palladium(0), 10 mg of cuprous iodide, 0.14 ml of triethylamine and 1.5 ml of N,N-dimethylformamide was heated under stirring in an oil bath kept at 100° C. for 2 hours in a nitrogen atmosphere. After cooling as it was, NH-silica gel was added to the reaction solution and the solvent was removed. The residue was subjected to NH-silica gel column chromatography using 2.5% methanol/ethyl acetate, to give 62 mg of the target compound.
