반응 단계
A mixture of the methyl ester of 4-[4-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-3-methoxy-2-pentenoic acid (0.5 g), 35% aqueous perchloric acid (5 ml.) and methylene dichloride (5 ml.) is stirred at RT for 4 days. Then the sollution is extracted with methylene dichloride. The residue is purified by prep. thin layer chromatography using 20% ethyl acetate/hexane to yield methyl 4-[4-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-3-oxopentanoate.
