Procedure

In a similar manner to Step 1 of Example 227, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0853 g, 0.185 mmol) was dissolved in dichloromethane (3.0 mL), and the solution was treated with triethylamine (0.129 mL, 0.924 mmol) and chloromethanesulfonyl chloride (0.0490 mL, 0.554 mmol) to obtain 4-chloromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0376 g, yield 35%).
