Phenol → Phenoxyacetic Acid

Participants

Reaction Steps

Phenol (d5) 4.6 g, ethyl chloroacetate (6.25 g), sodium iodide (7.5 g) and anhydrous potassium carbonate (7 g) were refluxed for 12 hours in dry acetone (50 ml). The mixture was then stirred into a large volume of water and the solution extracted with ether. Unreacted phenol was removed with cold 1N NaOH solution. The ether extract was dried over anhydrous sodium sulphate, filtered and concentrated under vacuum. The residual oil (8.0 g) without further purification, was hydrolyzed by 10% NaOH in D2O affording phenoxyacetic acid (4.5 g)
