Reaction Steps

In a similar manner to Step 2 of Example 16, 3-methoxymethoxy-4-dimethoxymethyl-N-(1-methyl-1-phenylethyl)benzamide (3.61 g, 9.67 mmol) was dissolved in THF (100 mL), and the solution was treated with TMEDA (4.70 mL, 31.0 mmol), sec-butyl lithium-hexane solution (1.03 mol/L, 30.0 mL, 30.9 mmol) and DMF (1.65 mL, 21.3 mmol), followed by purification by slurry using chloroform and hexane to obtain 4-methoxymethoxy-5-dimethoxymethyl-3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (2.95 g, yield 85%).
