Reaktionsschritte

(4,5-Dimethylfuran-2-yl)-(2-pyridyl)-methanone (1.6 g), methanol (15 ml), and a 28% aqueous ammonia solution (15 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-dimethyl-[2,2′]-bipyridin-3-ol (1.2 g, yield 75%).
