Benzyl Alcohol → 5-Benzyloxy-2-bromoisonicotinic acid ethyl ester

Participants

Reaction Steps

To a solution of benzylalcohol (1.5 g) in tetrahydrofuran (30 mL) was added sodium hydride (55%, 0.3 g) under ice cooling, and this mixture was stirred at same temperature for 5 minutes. To this reaction mixture was added a solution of 2-bromo-5-fluoroisonicotinic acid ethyl ester (2.9 g) in tetrahydrofuran (30 mL), and this mixture was stirred at room temperature for 2 hours. This reaction mixture was poured into water, and this mixture was extracted with ethyl acetate. This organic layer was washed with water and brine, dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: ethyl acetate/n-hexane) to give the title compound (2.4 g).
