In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0269 g, 0.0583 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0490 mL, 0.350 mmol) and trans-β-styrenesulfonyl chloride (0.0350 g, 0.175 mmol) to obtain 4-(trans-β-styrenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0770 g, yield 21%).
