4-Nitrophenol → 1-(4-Nitrophenoxy)propan-2-one

Participants

Reaction Steps

A mixture consisting of 35 g of 4-nitrophenol, 35 g of chloroacetone, 35 g of potassium carbonate, 1 g of potassium iodide and 500 ml of acetone was heated at reflux with stirring for 3 hr. Reaction mixture was concentrated underd reduced pressure; the concentrate was extracted with ethyl acetate; the ethyl acetate layer was washed consecutively with 5% aqueous solution of sodium hydroxide, water and saturated saline; and dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure; the residue was dissolved in 300 ml of ethanol, added with 100 ml of n-hexane; and subsequently left standing overnight at room temperature. Yellow crystals thus isolated were filtered off, dried and yielded 43.5 g of 4-nitrophenoxyacetone.
