実験手順

In a similar manner to Step 1 of Example 299, 4-hydroxy-7-(1-(tert-butoxycarbonyl)-5-[4-(2-tert-butyldimethylsilyloxyethyl)pyperazin-1-ylmethyl]indol-2-yl)isoindolinone (150 mg, 0.240-mmol) was suspended in dichloromethane (6.0 mL), and the suspension was treated with triethylamine (0.167 mL, 1.20 mmol) and trifluoromethanesulfonyl chloride (0.046 mL, 0.43 mmol) under ice-cooling, followed by purification by preparative thin-layer chromatography (chloroform/methanol=13/1) to obtain 4-trifluoromethanesulfonyloxy-7-{1-(tert-butoxycarbonyl)-5-[4-(2-tert-butyldimethylsilyloxyethyl)pyperazin-1-ylmethyl]indol-2-yl}isoindolinone (139 mg, yield 77%).
