반응 단계
A suspension of 1,4-difluoro-2-methyl-5-nitrobenzene (1.00 g), cyanoacetic acid benzyl ester (1.01 g) and potassium carbonate (1.76 g) in N,N-dimethylformamide (20.0 mL) was stirred at 60° C. for 1 day. To this reaction mixture was added 1 mol/L hydrochloric acid (25.4 mL), and this mixture was extracted with diethyl ether. This organic layer was washed with brine, and dried over anhydrous magnesium sulfate, and filtered. The solvent was removed under reduced pressure. This residue was washed with ethanol to give the title compound (1.54 g).
