In a similar manner to Step 4 of Example 16, 4-fluoro-3-hydroxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (1.17 g, 2.86 mmol) was dissolved in nitromethane (46 mL), and the solution was treated with trifluoroacetic acid (2.20 mL, 28.6 mmol) and triethylsilane (0.914 mL, 5.72 mmol), followed by purification by flash column chromatography (chloroform/methanol=100/0, 85/15) to obtain 4-fluoro-7-iodoisoindolinone (586 mg, yield 74%).
