In a similar manner to Step 1 of Example 304, 7-amino-4-(4-hydroxyphenyl)isoindolinone (182 mg, 0.760 mmol) was dissolved in acetonitrile (9.1 mL), and the solution was treated with tert-butyldimethylsilyl chloride (206 mg, 1.37 mmol) and DBU (0.205 mL, 1.37 mmol), followed by purification by flash column chromatography (chloroform) to obtain 7-amino-4-(4-tert-butyldimethylsilyloxyphenyl)isoindolinone (182 mg, yield 68%).
