반응 단계
In a similar manner to Step 1 of Example 227, 4-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.184 g, 0.399 mmol) was dissolved in dichloromethane (3.6 mL), and the solution was treated with triethylamine (0.250 mL, 1.79 mmol) and a-toluenesulfonyl chloride (0.152 g, 0.797 mmol), followed by purification by flash column chromatography (chloroform/methanol=85/15) to obtain 4-(a-toluenesulfonyloxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (0.0908 g, yield 37%).
