Reaction Steps

26.3 g of 7,8-difluoro-3-hydroxy-2-methylquinoline was dissolved in 200 mL of dimethylformamide. 27.2 g of 2,6-difluoroacetophenone and 24.0 g of potassium carbonate were added to the solution and the mixture was stirred for 4 hours at 100° C. After the thus obtained reaction solution was poured into ice water, and neutralized with dilute hydrochloric acid, the liquid was separated with ethyl acetate. The organic layer was concentrated and purified by silica gel column chromatography to obtain 17.0 g of 1-[2-fluoro-6-(7,8-difluoro-2-methylquinolin-3-yloxy)-phenyl]-ethanone.
