Reaktionsschritte
A mixture of 1.00 g of 1-(2,4-dihydroxy-3-propylphenyl) ethanone, 1.44 g of methyl 11-bromoundecanoate and 1.00 g of anhydrous potassium carbonate in 20 ml of anhydrous dimethyl formamide was stirred and heated at 75° for 2 hours. The usual workup followed by chromatography on 30 g of silica gel and elution with 10% ethyl acetate-toluene gave 1.48 g (76% yield) of 11-(4-Acetyl-3-hydroxy-2-propylphenoxy) undecanoic acid methyl ester, the titled compound, as an oil.
