1.0 g of 7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carbaldehyde was dissolved in 20 ml of DMF, and 2.0 g of potassium carbonate and 2.8 ml of ethyl(diethoxyphosphoryl)acetate were added, followed by overnight stirring at 60° C. The resulting reaction mixture was cooled to room temperature, water was added, and then the insoluble materials were collected by filtration to obtain 1.2 g of ethyl (2E)-3-[7-(cyclohexylamino)-1-cyclopentyl-6-fluoro-4-oxo-1,4-dihydroquinolin-3-yl]acrylate.
