Water → 2-Bromo-6-iodo-3-[(4-methoxyphenyl)methoxy]pyridine

참여 물질

반응 단계

Potassium carbonate (12 g) and 4-methoxybenzyl chloride (8.8 mL) were added to a solution of 2-bromo-6-iodopyridin-3-ol (12 g) in N,N-dimethylformamide (130 mL), and the mixture was stirred at room temperature for six hours. The reaction solution was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and filtered. The solvent was then evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=90:1→0:100) to give 2-bromo-6-iodo-3-[(4-methoxybenzyl)oxy]pyridine as a colorless powder (18 g, 100%).
