Water → 4-Methanesulfonyloxy-7-iodoisoindolinone

Participants

Reaction Steps

4-Hydroxy-7-iodoisoindolinone (400 mg, 1.45 mmol) was dissolved in dichloromethane (10 mL), and the solution was added with triethylamine (0.808 mL, 5.80 mmol) and added with methanesulfonyl chloride (0.224 mL, 2.89 mmol) at 0° C., followed by stirring at room temperature for 2 hours. The mixture was added with methanesulfonyl chloride (0.112 mL, 1.45 mmol) at 0° C., followed by stirring at room temperature for 2 hours. The reaction mixture was added with water and hexane. The precipitated solid was collected by filtration, washed with hexane and water and then dried under reduced pressure to obtain 4-methanesulfonyloxy-7-iodoisoindolinone (353 mg, yield 69%).
