Reaction Steps

Ethyl 7-[(E)-2-(4-isopropyl-1,3-thiazol-2-yl)-1-ethenyl]-4-oxo-1,4-dihydro-3-quinolinecarboxylate (368 mg, 1.00 mmol) was dissolved in dimethylformamide (6 ml), added with potassium carbonate (276 mg, 2.00 mmol) and 1-bromo-2-fluoroethane (0.223 ml, 3.00 mmol), and then the mixture was stirred overnight at 65° C. The reaction mixture was left stand for cooling and then diluted with ethyl acetate. The organic layer was washed with water and dried over anhydrous magnesium sulfate, and the solvent was evaporated. The resulting residue was purified by silica gel column chromatography (chloroform→chloroform:methanol=100:1) to obtain the title compound (254 mg, 61%) as colorless transparent oil.
