Reaction Conditions

Reaction Steps

The mixture of 2-bromo-5-hydroxypyridine (1 g, 5.75 mmol), bromocyclobutane (0.783 mL, 8.33 mmol) and potassium carbonate (1.589 g, 11.49 mmol) in DMF (11.5 mL) was stirred at 60° C. for 5 h, then at 80° C. for 14 h. The reaction mixture was diluted with EtOAc and washed with water, saturated NaHCO3, and brine. The organic layer was dried (Na2SO4) and concentrated. The crude product was purified by ISCO (40 g), eluting with a gradient of EtOAc/hexane 0-10% to provide to give 2-bromo-5-cyclobutoxypyridine (0.916 g, 4.02 mmol, 69.9% yield) as white solid. MS: M+ 228, 230. C9H10BrNO, MW=228.09
