実験手順
(4,5-Dimethylfuran-2-yl)-(6-methyl-pyridin-2-yl)methanone (690 mg), methanol (6 ml), and a 28% aqueous ammonia solution (6 ml) were placed in a sealed tube and were stirred at 160° C. overnight. The reaction solution was cooled to room temperature, the solvent was then removed by distillation under the reduced pressure, and the residue was purified by column chromatography using hexane-ethyl acetate to give 5,6,4′-trimethyl-[2,2′]bipyridin-3-ol (611 mg, yield 89%).
