Mode opératoire

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 (5.6 mL), and the solution was added with (3-aminocarbonylphenyl)boronic acid (89 mg, 0.54 mmol), [bis(diphenylphosphino)ferrocene]dichloropalladium (17.6 mg, 0.0216 mmol), potassium carbonate (93.0 mg, 0.675 mmol) and water (0.049 mL), followed by purification by preparative thin-layer chromatography (chloroform/methanol=5/1) to obtain 4-(3-carbamoylphenyl)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (36.1 mg, yield 47%).
