実験手順

In a similar manner to Step 1 of Example 433, 4-chloro-5-hydroxy-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)methylindol-2-yl]isoindolinone (100 mg, 0.202 mmol) was suspended in acetonitrile (5.0 mL), and the suspension was treated with cesium carbonate (98.7 mg, 0.303 mmol) and 1-chloro-3-iodopropane (0.026 mL, 0.242 mmol), followed by purification by flash column chromatography (chloroform/methanol=19/1, 4/1) to obtain 4-chloro-5-(3-chloropropoxy)-7-[1-(tert-butoxycarbonyl)-5-(piperidin-1-ylmethyl)indol-2-yl]isoindolinone (97.7 mg, yield 84%).
