In a similar manner to Step 2 of Example 16, 3-phenoxy-N-(1-methyl-1-phenylethyl)benzamide (4.00 g, 12.1 mmol) was dissolved in THF (160 mL), and the solution was treated with TMEDA (5.80 mL, 38.7 mmol), sec-butyllithium-hexane solution (0.99 mol/L, 39.0 mL, 38.7 mmol) and DMF (2.10 mL, 26.6 mmol), followed by purification by slurry using diisopropylether to obtain 4-phenoxy-3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (3.92 g, yield 90%).
