Reaction Steps

In a similar manner to Step 4 of Example 16, 4-methanesulfonyloxy-5-dimethoxymethyl-3-methoxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (226 mg, 0.393 mmol) was dissolved in nitromethane (5 mL), and the solution was added with trifluoroacetic acid (0.775 mL, 10.1 mmol) and triethylsilane (0.406 mL, 2.51 mmol), followed by stirring at 50° C. for 1 hour. The reaction mixture was added with water, ethyl acetate and hexane. The precipitated solid was collected by filtration and washed with water, followed by drying under reduced pressure to obtain 4-methanesulfonyloxy-5-methoxymethyl-7-iodoisoindolinone (113 mg, yield 72%).
