반응 단계
Concentrated sulfuric acid (0.08 mL) was added slowly to a mixture of 5-chlorosalicylic acid (13.35 g, 77 mmol) and acetic anhydride (20 mL). After the reaction mixture was solidified, it was poured into ice water and extracted with ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous sodium sulfate. The residue obtained by evaporation of the solvent under reduced pressure was washed with n-hexane under suspension to give the title compound (15.44 g, 93.0%) as a white crystal.
