실험 절차

To a stirred solution of 4-chloro-3-nitroaniline (17.3 g, 100 mmol) in DCM (150 mL) was added dropwise acetic anhydride (14 mL, 150 mmol) at ambient temperature. The mixture was stirred at ambient temperature for 2.5 h. The solvent was removed in vacuo, and Et2O was added to the residue. The precipitate was collected by filtration, washed with Et2O, and dried in vacuo to give N-(4-chloro-3-nitrophenyl)acetamide (20.7 g, 96%), which was used without further purification.
