A mixture of 40 g. of 4-benzyloxyphenol, 45.8 g. of ethyl bromoacetate, 40.0 g. of potassium carbonate, 2 g. of potassium iodide and 400 ml. of acetone was heated at reflux for 24 hours. The reaction mixture was filtered and concentrated in vacuo, and the residue was recrystallized from an ether-petroleum ether mixture to give 50 g. of ethyl 4-benzyloxyphonoxyacetate, m.p. 72°-73° C.
