3-Hydroxypyridine → HCID 178505469, compound

Participants

Reaction Steps

The compound of Example 1 (150 mg) was dissolved in THF (5 mL), and thionyl chloride (60 mg) and pyridine (146 mg) were added thereto. The mixture was stirred for 30 minutes at room temperature, and then 3-hydroxypyridine (87 mg) and potassium hydroxide (65 mg) were added thereto. The mixture was heated to reflux for 30 minutes while being stirred. A 10% aqueous solution of sodium hydroxide was added to the reaction mixture, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate. After distilling off the solvent under reduced pressure, the residue was purified by silica gel column chromatography (60% to 100% ethyl acetate/hexane), and thus the title compound (19 mg) was obtained as a yellow amorphous material.
