4-Hydroxy-5-methoxy-7-iodoisoindolinone (0.465 g, 1.52 mmol) was dissolved in acetonitrile (10.0 mL), and the solution was added with triethylamine (0.850 mL, 6.09 mmol) and 2-pyridinesulfonyl chloride hydrochloride (0.488 g, 2.28 mmol), followed by stirring at room temperature for 5 hours. The reaction mixture was added with water (8.0 mL) and stirred at room temperature for 30 minutes. The precipitated crystal was collected by filtration to obtain 4-(2-pyridinesulfonyloxy)-5-methoxy-7-iodoisoindolinone (0.468 g, yield 69%).
