Reaction Steps

A mixture of 127 mg of 3-(3-benzyl-5-bromo-2-pyridyl)ethynyl-3-quinuclidinol (Example 22-a), 61.4 mg of 3-thiopheneboronic acid, 55.4 mg of tetrakis (triphenylphosphine)palladium(0), 2 ml of toluene, 0.5 ml of methanol and 1 ml of aqueous 2 mol sodium carbonate solution was stirred at 80° C. for 2 hours in a nitrogen atmosphere. 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 3% methanol/ethyl acetate, to give 83.9 mg of the target compound.
