実験手順

A solution comprising 14.8 grams (0.1 mole) of 2,6-dichloropyridine, 12.4 grams (0.1 mole) of 4-methoxyphenol and 8.4 grams (0.15 mole) of flake potassium hydroxide in 100 milliliters of a 1:1 mixture of monoglyme and hexamethylphosphoramide was stirred for 24 hours at room temperature. The resulting mixture was diluted with water and thoroughly extracted with hexane. The extract was washed with water, dried and concentrated under reduced pressure. The residue was recrystallized from pentane giving 14.5 grams (64 percent of theoretical) of 2-chloro-6-(4-methoxyphenoxy)pyridine which melted at 63°-65° C.
