実験手順
To a solution of methyl 3-chloro-4-(3-(4-ethyl-8-propyl-7-coumarinoxy)propylthio)phenylacetate (Example 1; 82 mg, 0.1677 mmol) in 1.2 mL methanol:water (1:1) was added a 0.5M solution of potassium hydroxide in methanol. The mixture was heated to 40° C. for two hours at which time the mixture was acidified to pH=3 with 1M aqueous hydrochloric acid. The aqueous solution was extracted with ethyl acetate and the combined organics were dried over magnesium sulfate, filtered, and the crude residue was purified by flash chromatography on silica gel (30% ethyl acetate/hexane/1% acetic acid) which provided the title compound.
