Reaction Steps

2-Chloro-3-trifluoromethylpyridine (1.0 g), methyl 4-hydroxybenzenecarboxylate (838.3 mg) and potassium carbonate (2.28 g) were suspended in acetonitrile (10 mL), and heated under reflux for 27 hours, and then 2-chloro-3-trifluoromethylpyridine (1.0 g) was added thereto and further heated under reflux for 24 hours. Water (100 mL) was added to the reaction liquid, extracted with ethyl acetate (100 mL), and the organic layer was washed with aqueous 2 N sodium hydroxide solution (100 mL), water (100 mL) and saturated saline water (100 mL) in that order, dried with magnesium sulfate and evaporated under reduced pressure to obtain a pale yellow oil. The resulting oil was purified through silica gel column chromatography (hexane/ethyl acetate=8/2) to obtain the entitled compound (1.35 g) as a pale yellow oil.
