Reaction Steps

Methyl 3,5-bis(methoxymethoxy)-2-(4-methoxybenzoyl)-phenylacetate (490 mg, 1.2 mmol) obtained in Example 134, Step 2 was dissolved in N,N-dimethylformamide (10 mL), and N-bromosuccinimide (220 mg, 1.2 mmol) was added thereto, followed by stirring at room temperature for 3 hours. To the reaction mixture was added water for liquid separation, and the aqueous layer was extracted with ethyl acetate. The organic layers were combined, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane=1/4-1/1) to obtain methyl 3,5-bis(methoxymethoxy)-2-bromo-6-(4-methoxybenzoyl)phenylacetate (520 mg, 89%).
