Методика

In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0291 g, 0.0630 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0530 mL, 0.378 mmol) and 2,4-dichlorobenzenesulfonyl chloride (0.0436 g, 0.189 mmol) to obtain 4-(2,4-dichlorobenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0232 g. yield 55%).
