In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0298 g, 0.0646 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0540 mL, 0.388 mmol) and 3-trifluoromethylbenzenesulfonyl chloride (0.0310 mL, 0.194 mmol) to obtain 4-(3-trifluoromethylbenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0251 g, yield 58%).
