Reaction Steps

In a similar manner to Step 2 of Example 16, 3-chloro-4-methoxy-N-(1-methyl-1-phenylethyl)benzamide (500 mg, 1.65 mmol) was dissolved in THF (20 mL), and the solution was treated with TMEDA (0.80 mL, 5.3 mmol), sec-butyl lithium-hexane solution (0.99 mol/L, 5.3 mL, 5.3 mmol) and DMF (0.281 mL, 3.63 mmol), followed by purification by slurry using diisopropylether to obtain 4-chloro-5-methoxy-3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (385 mg, yield 71%).
