実験手順

After 30 ml of acetonitrile was added to 3.0 g of 8-fluoro-3-hydroxyquinoline, 3.1 g of potassium carbonate and 3.5 g of 2,6-difluoroacetophenone were added. After the reaction solution was heated under reflux for 3 hours, the reaction solution was filtered with CELITE. After the filtrate was extracted with ethyl acetate, the organic layer was concentrated and purified by silica gel column chromatography to obtain 3.0 g of 2-fluoro-6-(8-fluoroquinolin-3-yloxy)-benzaldehyde (Compound Number 341).
