Methanol → 4-[2-Chloro-4-(trifluoromethyl)phenoxy]phenol

Participants

Reaction Steps

4-Benzyloxyphenyl 2-chloro-4-trifluoromethylphenyl ether (25 g., 0.066 mole), purified by recrystallization from methanol, ethyl acetate (200 ml.) and 10% palladium on charcoal (1.0 g.) are charged to a 2-liter Paar hydrogenation bottle and shaken in a hydrogen atmosphere (40-45 psi) until hydrogen uptake ceases. The catalyst is then removed by filtration and the solvent and toluene are removed in vacuo to give 17.9 g. (94% yield) of 4-(2-chloro- 4-trifluoromethylphenoxy)phenol, mp 55°-6 ° C.
