In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0315 g, 0.0682 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0570 mL, 0.409 mmol) and 4-methoxybenzenesulfonyl chloride (0.0420 g, 0.205 mmol) to obtain 4-(4-methoxybenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0194 g, yield 45%).
