In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0295 g, 0.0639 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0530 mL, 0.383 mmol) and 4-chlorobenzenesulfonyl chloride (0.0400 g, 0.192 mmol) to obtain 4-(4-chlorobenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0167 g, yield 41%).
