Reaction Steps
31.6 g of 2-benzyloxyethyl-2-(4-hydroxyphenoxy)propionate were dissolved in 100 ml of dimethylsulfoxide, 15.2 g of potassium carbonate were added thereto, then the mixture was heated at 90° C. for one hour with stirring. 20.0 g of 2-chloro-5-trifluoromethylpyridine were added dropwise to this solution which was then maintained at 90° C. for a further two hours. After cooling the reaction solution to room temperature, it was poured into ice-water, then extracted with ether. The ether layer was dried and filtered, and the ether was distillated off. The end product of 2-benzyloxyethyl-2-[4-(5-trifluoromethyl-2-pyridyloxy)-phenoxy]propionate (a compound also produced in Example 20) was obtained in a yield of 41.0 g (m.p. 44°-47° C.).
