Reaction Steps
To a solution of (8E,12E,14E)-3,6,16,21-tetrakis(1-ethoxyethoxy)-7-hydroxy-6,10,12,16,20-pentamethyl-18,19-epoxytricosa-8,12,14-trien-11-olide (10 mg, 12.5 μmol) obtained in Example 3-2 in pyridine (0.5 mL) were added N,N-dimethylaminopyridine (8 mg, 62.5 μmol) and benzyl chloride (17.6 mg, 125 μmol) at room temperature, and the reaction mixture was stirred at the same temperature under nitrogen atmosphere for 12 hours. The reaction mixture was diluted with ethyl acetate and washed with a saturated aqueous solution of ammonium chloride and brine. The organic layer was dried over anhydrous magnesium sulfate and evaporated. The resulting residue was purified by silica gel column chromatography (Kanto silica gel 60N, 40 to 100 μm; ethyl acetate:hexane=25:75) to give the title compound (6 mg, 55%) as a colorless oil.
