실험 절차

A mixture of 5-bromo-4,6-dimethylpyridin-2-ol (7 g), methyl iodide (21.6 mL) and silver carbonate (19.1 g) was stirred in a chloroform solvent (140 mL) at room temperature for 36 hours. The reaction mixture was subjected to silica gel pad and eluted with a mixed solvent of (ethyl acetate:n-heptane=2:8). The resulting solution was concentrated under reduced pressure to give the title compound (6.98 g).
