الإجراء التجريبي

In a similar manner to Step 1 of Example 152, 4-trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (80.0 mg, 0.135 mmol) was dissolved in dimethoxyethane (9.6 mL), and the solution was treated with 4-(hydroxymethyl)phenylborate (62.0 mg, 0.405 mmol), [bis(diphenylphosphino)ferrocene]dichloropalladium (22 mg, 0.027 mmol), potassium carbonate (93.0 mg, 0.675 mmol) and water (0.098 mL), followed by purification by preparative thin-layer chromatography (chloroform/methanol=6/1) to obtain 4-[4-(hydroxymethyl)phenyl]-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (47.7 mg, yield 64%).
