2-Butanone, 1-(4-chlorophenoxy)-3,3-dimethyl- → 1-(4-Chlorophenoxy)-3,3-dimethylbutan-2-ol

Participants

Reaction Steps

Into a 200-ml egg plant type flask were placed 9.0 g of 1-(p-chlorophenoxy)-3,3-dimethyl-2-butanone and 80 ml of methanol, and 0.8 g of sodium borohydride was further placed into the flask with cooling and stirring. After stirring the mixture at room temperature for 1 hour, the reaction mixture was concentrated in a vacuum, and 50 ml of water was added to the resulting residue, followed by extraction with 30 ml of ether twice. The combined ethereal extract was washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated in a vacuum. The residue was purified by silica gel column chromatography, giving 8.5 g of the above-identified desired compound.
