実験手順

(4,5-Dimethylfuran-2-yl)-(6-methyl-pyridin-2-yl)-methanone (810 mg), methanol (7 ml), and a 28% aqueous ammonia solution (7 ml) were placed in a sealed tube, and the mixture was 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 5,6,6′-trimethyl-[2,2′]bipyridin-3-ol (753 mg, yield 93%).
