Reaction Conditions

Reaction Steps

4-Methoxymethoxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (463 mg, 1.06 mmol) was dissolved in 10% hydrogen chloride-methanol solution (14 mL), and the solution was stirred at 70° C. for 2.5 hours. Then, the solution was added with 10% hydrogen chloride-methanol solution (4.3 mL) and further stirred at 2.5 hours. The reaction mixture was added with chloroform and purified by slurry. The solid was collected by filtration and washed with chloroform/methanol (9/1). The obtained solid was dried under reduced pressure to obtain 4-hydroxy-7-iodoisoindolinone (248 mg, yield 85%).
