반응 단계
A mixture of 4-(2-chloro-4-trifluoromethylphenoxy) phenol (1.16 g), ethyl 4-bromo-3-methoxy-2-pentenoate (1.74 g) and potassium carbonate (0.73 g) in DMF (5 ml.) is heated at about 130° for 2 hours. Thereafter, DMF is removed. The residue is filtered and washed with methylene dichloride. The filtrate is washed, dried and evaporated to dryness. The oily residue is subjected to prep. thin layer chromatography using 20% ethylacetate/hexane to yield the ethyl ester of 4-[4-(2-chloro-4-trifluoromethylphenoxy) phenoxy]-3-methoxy-2-pentenoic acid, MS m/e 444 (M+).
