Procedure

Commercial available 4-phenoxy-aniline (4.16 g, 20.8 mmol) was dissolved in dichloromethane (100 mL), and triethylamine (3.05 g, 31.1 mmol) and acetic anhydride (2.22 g, 20.8 mmol) were added in drops. The mixture was stirred for 1 h at 0° C. to room temperature. After completion of the reaction, the mixture was filtered using dichloromethane and crystallized to give the title compound (4.50 g, 18.6 mmol)
