Reaction Steps
A mixture comprising 90.5 grams (0.5 mole) of 2-chloro-6-trifluoromethylpyridine, 65 grams (0.55 mole) of 4-methoxyphenol and 36.4 grams (0.55 mole) of 85 percent potassium hydroxide was stirred in 1 liter of a 1:1 mixture of monoglyme and hexamethylphosphoramide for 1 hour at room temperature and thereafter heated overnight at reflux. The resulting mixture was diluted with water and extracted with hexane. The hexane extract was washed with a dilute sodium hydroxide solution followed by water washing. The extract was dried and concentrated under reduced pressure to give 127 grams (94 percent of theoretical) of 2-trifluoromethyl-6-(4-methoxyphenoxy)pyridine.
