実験手順

To a solution of methyl 4-hydroxy-3-nitrobenzoate (2.0 g) in acetic acid (15 mL) was added iodine monochloride (1.65 mg) in acetic acid, and the mixture was stirred at 100° C. for 1.5 h. After cooling to room temperature, the mixture was poured into water (200 mL), and stirred for 30 min. The mixture was filtered and washed with water and hexanes. The yellow powder was collected by filtration and dried in vacuum oven overnight to give 2.99 g of the title compound: 1H NMR (300 MHz, CDCl3) δ 11.68, 8.81, 8.72, 3.96.
