Procedure

4-Methoxy-benzaldehyde (1 g, 7.34 mmol) was added to a mixture of ammonium nitrate (0.58 g, 7.34 mmol) and trifluoroacetic anhydride (3.56 mL, 25.69 mmol), which was cooled to 0° C. The reaction mixture was stirred at 0° C. for 15 min and then allowed to stir at room temperature for about 7 h. Ice was added and stirred for 30 min. The solid obtained was filtered, washed with cold water (3×5 mL) and dried.
