Procedure
Nitric acid (100 mL) was cooled to 0° C., 4-benzyloxy-3-methoxybenzaldehyde (20 g, 82.55 mmol) was added dropwise, and the mixture was stirred at room temperature for 2 hours. After completion of the reaction, distilled water was added thereto and the mixture was stirred for 30 min, followed by filtration of the solid to obtain the title compound (20.52 g, 87%).
