Reaction Steps

A mixture of 4-(2-chloro-4-trifluoromethylphenoxy) phenol (6.9 mmol.), methyl 4-bromo-3-methoxy-2-pentenoate (8.9 mmol.) and potassium carbonate (1.5 equis.) in acetone (15 ml.) is refluxed for 48 hours. After filtration, the filtrate was concentrated and the residue chromatographed on silica gel using 20% ethylacetate/hexane to give the methyl ester of 4-[4-(2-chloro-4-trifluoromethylphenoxy) phenoxy]-3-methoxy-2-pentenoic acid.
