4-Chloro-1-naphthol → 2-Chloro-1-(4-((4-chloronaphthyloxy)methyl)phenoxy)ethane

Participants

Reaction Steps

A stirred solution of 8.4 grams (0.045 mole) of the mixture of (4-(2-bromoethoxy)phenyl)methan-1-ol and (4-(2-chloroethoxy)phenyl)methan-1-ol, 8.1 grams (0.045 mole) of 4-chloronaphthol, and 13.7 mL (0.054 mole) of tributylphosphine in 500 mL of THF was cooled in an ice bath and 12.6 grams (0.049 mole) of 1-1′-(azodicarbomyl)dipiperidine was added. Upon completion of addition, the reaction mixture was allowed to warm to ambient temperature where it stirred for 24 hours. After this time, the solvent was reduced under reduce pressure, yielding a solid. The solid was purified by column chromatography on silica gel, yielding 15 grams of crude product. The crude product was further purified by column chromatography on silca gel, yielding 6.7 grams of title compound.
