Reaction Conditions

Reaction Steps

To an N,N-dimethylformamide (30.0 mL) solution of 3-hydroxypyridine (3.00 g, 31.5 mmol) and 4-fluorobenzaldehyde (5.08 g, 41.0 mmol) was added potassium carbonate (8.71 g, 63.0 mmol) under nitrogen atmosphere, which was stirred for 17 hours at 70° C. The reaction mixture was then cooled to room temperature and water was added thereto, followed by extraction with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, and the solvent was evaporated under a reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:heptane=1:1->3:1) to obtain the title compound (1.70 g, 27.1%).
