Triethylamine → 4-(2-Trifluoromethyl-5-methyl-3-furansulfonyloxy)-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 (0.0277 g, 0.0600 mmol) was dissolved in acetonitrile (0.650 mL), and the solution was treated with triethylamine (0.0540 mL, 0.390 mmol) and 5-methyl-2-trifluoromethyl-3-furansulfonyl chloride (0.0486 g, 0.195 mmol) to obtain 4-(2-trifluoromethyl-5-methyl-3-furansulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0092 g, yield 23%).
