Reaction Steps

After 0.91 g of 7,8-difluoro-3-hydroxyquinoline and 0.94 g of 2,6-difluoroacetophenone were dissolved in 10 ml of dimethylformamide, 0.9 g of potassium carbonate was added. The reaction solution was heated to 100° C. and the mixture was stirred for 4.5 hours. Dilute hydrochloric acid was added to the reaction solution and the solution was separated by ethyl acetate. The organic layer was concentrated and purified by silica gel column chromatography to obtain 0.64 g of 1-[2-(7,8-difluoroquinolin-3-yloxy)-6-fluoro-phenyl]-ethanone (Compound Number 391).
