反応手順
In a similar manner to Step 1 of Example 152, 4-trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (50.0 mg, 0.0842 mmol) was dissolved in dimethoxyethane (4 mL), and the solution was treated with 3,4-methylenedioxybenzeneboronic acid (70.0 mg, 0.421 mmol). [bis(diphenylphosphino)ferrocene]dichloropalladium (13.7 mg, 0.0168 mmol), potassium carbonate (116 mg, 0.842 mmol) and water (0.060 mL), followed by purification by preparative thin-layer chromatography (chloroform/methanol/acetonitrile=8/0.5/0.5 to 0.4/0.5/0.5) to obtain 4-(benzo[1,3]dioxol-5-yl)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (22.2 mg, yield 47%).
