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 (300 mg, 0.505 mmol) was dissolved in dimethoxyethane (21 mL), and the solution was treated with 4-(4,4,5,5-tetramethyl-1,3,2-dioxaboran-2-yl)phenol (222 mg, 1.01 mmol), [bis(diphenylphosphino)ferrocene]dichloropalladium (33.0 mg, 0.0404 mmol), potassium carbonate (349 mg, 2.53 mmol) and water (0.182 mL), followed by purification by flash column chromatography (chloroform/methanol=90/10 to 80/20) to obtain 4-(4-hydroxyphenyl)-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (179 mg, yield 66%).
