実験手順
Following General Procedure G, a solution of ethyl 7-(7-ethoxy-4-ethyl-2,2-dimethyl-2H-chromen-6-yl)-6-fluoro-3-methyl-octa-2E,4E,6E-trienoate (Compound 110, 9.0 mg, 0.02 mmol) in ethanol and THF was hydrolyzed with 1M NaOH. Purification by flash chromatography (silica gel, 75:25 hexane/ethyl acetate) afforded the title compound as a white solid.
