Procedure

A solution of acetic anhydride (14.3 mL, 151 mmol) and formic acid (22.8 mL, 605 mmol) was stirred at room temperature for 1 h. Methyl (4-aminophenyl)acetate (5.00 g, 30.3 mmol) was added and the resulting mixture was stirred overnight. Saturated aqueous sodium bicarbonate (10 mL) was added and the resulting mixture was extracted with DCM (2×10 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated under reduced pressure to give the title compound (4.31 g) as a yellow oil, which was used in the next reaction without further purification.
