In a similar manner to Step 4 of Example 16, 3-hydroxy-4-chloro-5-fluoro-7-iodo-2(1-methyl-1-phenylethyl)isoindolinone (806 mg, 1.81 mmol) was dissolved in nitromethane (32 mL), and the solution was treated with trifluoroacetic acid (1.40 mL, 18.1 mmol) and triethylsilane (0.578 mL, 3.62 mmol), followed by purification by slurry using diisopropylether to obtain 4-chloro-5-fluoro-7-iodoisoindolinone (477 mg, yield 85%).
