Procedure

In a similar manner to Step 1 of Example 152, 7-amino-4-bromoisoindolinone (150 mg, 0.661 mmol) was dissolved in dimethoxyethane (10.5 mL), and the solution was treated with 3-(4,4,5,5-tetramethyl-1,3,2-dioxaboran-2-yl)phenol (291 mg, 1.32 mmol), [bis(diphenylphosphino)ferrocene]dichloropalladium (43 mg, 0.053 mmol), potassium carbonate (455 mg, 3.31 mmol) and water (0.24 mL), followed by purification by slurry using chloroform to obtain 7-amino-4-(3-hydroxyphenyl)isoindolinone (140 mg, yield 88%).
