Reaction Steps

To a three-necked 100 ml flask equipped for reflux and fitted with a mechanical stirrer was added 10 ml (0.12 mol) of diemthyl sulfite, 2.0 g (0.014 mol) of potassium carbonate, 10 ml dimethylformamide and 5.0 g (0.033 mol) of p-acetamidophenol. The mixture was heated to 100° C. for six hours then quenched while hot with 200 ml of water. The solution was made basic with dilute caustic and the organic materials were extracted into methylene chloride. The extracts were concentrated in vacuo to give 3.2 g of p-acetamidoanisole.
