In a similar manner to Step 1 of Example 227, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0843 g, 0.183 mmol) was dissolved in dichloromethane (3.0 mL), and the solution was treated with triethylamine (0.127 mL, 0.913 mmol) and cyclohexylmethanesulfonyl chloride (0.108 g, 0.548 mmol) to obtain 4-cyclohexylmethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0914 g, yield 80%).
