Reaktionsschritte
In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0316 g, 0.0685 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0570 mL, 0.411 mmol) and 3-chloropropanesulfonyl chloride (0.0250 mL, 0.205 mmol) to obtain 4-(3-chloro-n-propanesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0101 g, yield 24%).
