In a similar manner to Step 1 of Example 429, 4-chloro-5-hydroxy-7-iodoisoindolinone (283 mg, 0.916 mmol) was dissolved in DMF (8.4 mL), and the solution was treated with potassium carbonate (190 mg, 1.37 mmol), tetrabutylammonium iodide (33.8 mg, 0.092 mmol) and 3-bromopropylcarbamic acid tert-butyl ester (654 mg, 2.75 mmol). The reaction mixture was added with water. The obtained solid was collected by filtration and purified by slurry using hexane and diisopropylether to obtain 4-chloro-5-[3-(tert-butoxycarbonylamino)propoxy]-7-iodoisoindolinone (350 mg, yield 84%).
