Reaction Steps

Methyl 3,5-diallyloxy-2-iodo-6-(4-methoxybenzoyl)phenylacetate (80 mg, 0.15 mmol) obtained in Example 15, Step 2 was dissolved in 1,4-dioxane (1.0 mL), and selenium dioxide (36 mg, 0.34 mmol) and acetic acid (0.028 mL; 0.46 mmol) were added thereto, followed by stirring at 75° C. for half a day. The reaction mixture was poured into a saturated aqueous solution of sodium hydrogencarbonate, followed by extraction with chloroform. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resulting residue was purified by preparative thin layer chromatography (chloroform/methanol=9/1) to obtain Compound 15 (1.2 mg, 8.2%).
