Reaction Steps

In a similar manner to Step 1 of Example 227, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.126 g, 0.274 mmol) was dissolved in acetonitrile (6.0 mL), and the solution was treated with triethylamine (0.0760 mL, 0.548 mmol) and 2-chlorobenzenesulfonyl chloride (0.0867 g, 0.411 mmol) to obtain 4-(2-chlorobenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.130 g, yield 75%).
