Reaction Steps

290 mg of 1-[(2-methoxy-3-pyridyl)methyl]-4-[2-(3-bromo-2-thienyl)-2-oxoethyl]piperidine obtained in Example 73, 173 mg of phenylboric acid and 42 mg of tetrakis(triphenylphosphine)palladium were suspended in 5.6 ml of toluene, 1.4 ml of methanol and 2.8 ml of 2 M sodium carbonate, and the mixture was heated under reflux for 3 hours under nitrogen flow. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, and then dried over anhydrous magnesium sulfate. The solvent was evaporated, and the crude product was purified by silica gel column chromatography (ethyl acetate), to give 290 mg of the title compound as a yellow oil.
