실험 절차

In a similar manner to Step 1 of Example 299, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (300 mg, 0.765 mmol) was dissolved in dichloromethane (12 mL), and the solution was treated with triethylamine (0.533 mL, 3.83 mmol) and trifluoromethanesulfonyl chloride (0.138 mL, 1.30 mmol) under ice-cooling, followed by purification by flash column chromatography (chloroform/methanol=100/0 to 98/2) to obtain 4-trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-formylindol-2-yl]isoindolinone (249 mg, yield 62%).
