In a similar manner to Step 2 of Example 16. N-(1-methyl-1-phenylethyl)benzamide (5.00 g, 20.9 mmol) was dissolved in THF (200 mL), and the solution was treated with TMEDA (10.0 mL, 66.9 mmol), sec-butyl lithium-hexane solution (1.01 mol/L, 66.0 mL, 66.9 mmol) and DMF (3.60 mL, 46.0 mmol), followed by purification by slurry using diisopropylether to obtain 3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (5.40 g, yield 97%).
