Benzyl Chloride → 1-(3-(Phenylmethoxy)phenyl)ethan-1-one

Participants

Reaction Steps

A mechanically stirred mixture of 1 kg. (7.35 mole) of 3-hydroxyacetophenone, 1.035 kg. (7.5 mole) anhydrous potassium carbonate and 0.945 kg. (7.5 mole) of benzylchloride in 4.1 of acetone was heated at reflux for 24 hours after which 0.1035 kg. (0.75 mole) portion of potassium carbonate and 0.0945 kg. (0.75 mole) portion of benzylchloride were added and refluxing continued. This addition was repeated after 72 hours of refluxing and refluxing continued for 96 hours. The reaction was cooled, filtered and the filtrate concentrated on a rotovapor. The filtrate was then treated with 0.202 kg. (2.0 mole) triethylamine and stirred overnight. The reaction was diluted with 1 liter ether and filtered. The filtrate was evaporated and the residue distilled to yield 1.429 kg. (86%) of the title compound as an oil.
