Procedure

To a solution of 40 ml of methanol, 1.19 g of sodium methoxide and 3.21 g of p-chlorophenol is added 7.4 g of methyl α-bromo-α-[p-(p-cyanophenoxy)phenyl]acetate in 15 ml of benzene. The mixture is refluxed for 20 hours, poured into ice and water, and extracted with ether. The ether extracts are washed with 10% potassium carbonate and with water. Drying over magnesium sulfate and removal of the solvent under vacuum gives a tan oil. Filtration once through silica gel with chloroform as solvent gives an oil in the first fractions. The oil is filtered through silica gel with benzene as the solvent to give, in the first fractions, a pale yellow oil.
