実験手順

In a similar manner to Step 3 of Example 16, 4-methoxymethoxy-5-methyl-3-hydroxy-2-(1-methyl-1-phenylethyl)isoindolinone (2.94 g, 8.61 mmol) was dissolved in THF (110 mL), and the solution was treated with TMEDA (4.20 mL, 27.8 mmol), sec-butyl lithium-hexane solution (0.95 mol/L, 29.0 mL, 27.6 mmol) and iodine (2.62 g, 10.3 mmol), followed by purification by flash column chromatography (hexane/ethyl acetate=4/1 to 7/3 to 6/4). The obtained solid was purified by slurry using hexane to obtain 4-methoxymethoxy-5-methyl-3-hydroxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (2.40 g, yield 60%).
