Triethylamine → 4-(4-Tert-butylbenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone

Participants

Reaction Steps

In a similar manner to Step 1 of Example 233, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0294 g, 0.0637 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0530 mL, 0.382 mmol) and 4-tert-butylbenzenesulfonyl chloride (0.0440 g, 0.191 mmol) to obtain 4-(4-tert-butylbenzenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0180 g, yield 43%).
