Reaction Steps

In a similar manner to Step 1 of Example 289, 4-hydroxy-5-formyl-3-methoxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (325 mg, 0.720 mmol) was dissolved in dichloromethane (10 mL), and the solution was treated with triethylamine (0.401 mL, 2.88 mmol) and methanesulfonyl chloride (0.111 mL, 1.43 mmol), followed by purification by flash column chromatography (hexane/ethyl acetate=95/5 to 80/20) to obtain 4-methanesulfonyloxy-5-formyl-3-methoxy-7-iodo-2-(1-methyl-1-phenylethyl)isoindolinone (381 mg, yield 58%).
