Reaction Steps
In a similar manner to Step 1 of Example 227, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0728 g, 0.158 mmol) was dissolved in acetonitrile (2.0 mL), and the solution was treated with triethylamine (0.0660 mL, 0.473 mmol) and 2-pyridinesulfonyl chloride (0.0680 g, 0.315 mmol) to obtain 4-(2-pyridinesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.698 g, yield 73%).
