実験手順

A mixture of (4-benzyl-4-hydroxypiperidin-1-yl)(2-chloropyridin-3-yl)methanone (5.0 g), tetrakis(triphenylphosphine)palladium(0) (0.87 g), pyridine-4-boronic acid (2.2 g), sodium carbonate (4.8 g), DMF (50 mL) and water (10 mL) was stirred overnight at 100° C. under a nitrogen atmosphere. To the reaction mixture was added saturated brine, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (3.4 g). The compound was crystallized from ethyl acetate/heptane to give the title compound as crystals.
