Reaction Steps
A mixture of 15.04 grams (g) (0.076 mole (m)) of 2-dichloromethyl-6-chloropyridine, 39.50 g (0.32 m) of p-methoxyphenol and 18.14 g (0.32 m) of potassium hydroxide in 100 milliliters (ml) of dimethylsulfoxide was heated, with stirring, for 72 hours. The resulting mixture was cooled to 25° C., diluted with water and extracted with 1,1,1-trichloroethane. The extract was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The concentrate was subjected to Kugelrohr distillation removing as impurities any material boiling up to 200° C. at 0.05-1 millimeter of mercury (mm). The 2-[bis-(4-methoxyphenoxy)methyl]-6-(4-methoxyphenoxy)pyridine product was removed as the residue of the distillation and was a brown thick oil. The product was obtained in a yield of 25.3 g and upon analysis, was found to have carbon, hydrogen and nitrogen contents of 70.80, 5.37 and 3.09 percent, respectively, as compared with the theoretical contents of 70.59, 5.45 and 3.05 percent, respectively, as calculated for the above named compound.
