Reaction Steps
A mixture of 3-bromo-5-(tetrahydro-2H-pyran-4-ylmethoxy)pyridine (300 mg), copper(II) sulfate pentahydrate (130 mg), bronze (100 mg), sodium hydroxide (700 mg), and water (5 mL) was stirred in an autoclave at 210° C. for 6 hours. The reaction mixture was cooled to room temperature, followed by addition of methanol, and insolubles were removed by filtration. The filtrate was concentrated under reduced pressure and extracted with chloroform. The aqueous layer was neutralized by addition of 1M hydrochloric acid (3.5 mL), followed by extraction with ethyl acetate. The organic layers were combined and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain 5-(tetrahydro-2H-pyran-4-ylmethoxy)pyridin-3-ol (137 mg).
