실험 절차

A solution of 4-fluoro-2-methylaniline (about 1 g) in chloroform (5 ml) was added dropwise to a solution of ethyl 3-ethoxy-2-(2',5'-difluoro-3'-methyl-4'-nitrobenzoyl)acrylate (2.0 g) in chloroform (10 ml) at room temperature (while confirming the disappearance of the acrylate by tlc). After the mixture was stirred for 10 minutes, the solvent and the like were distilled off. Potassium carbonate (800 mg) was added to a solution of the whole amount of the residue in dimethylformamide (3 ml), and the mixture was stirred at 110° C. for 20 minutes. Chloroform and water were added to the reaction mixture to collect an organic layer. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was distilled off. Ethanol was added to the residue to disperse it therein, and filtration was conducted to obtain the title compound (1.1 g) as a pale yellow powder.
