Procedimiento

In a similar manner to Step 1 of Example 429, 4-chloro-5-hydroxy-7-iodoisoindolinone (70.0 mg, 0.226 mmol) was dissolved in DMF (2.1 mL), and the solution was treated with potassium carbonate (93.8 mg, 0.679 mmol) and tert-butyl(4-iodobutoxy)dimethylsilane (0.176 mL, 0.679 mmol), followed by purification by flash column chromatography (chloroform/methanol=99/1, 19/1) to obtain 4-chloro-5-[4-(tert-butyldimethylsiloxy)butoxy]-7-iodoisoindolinone (94.2 mg, yield 84%).
