A solution of ethyl 4-methylphenoxyacetate, which may be prepared as set forth by S. G. Powell and R. Adams in J. Am. Chem. Soc., 42, pages 646-658 (1920), (18.21 g, 0.094 mole) in 100 ml of dry CCl4 was stirred and refluxed under a 350 watt tungsten lamp. A solution of 15 g (0.094 mole) of bromine in 100 ml of CCl4 was added by means of an addition funnel over a period of 30 minutes. The colorless reaction mixture was evaporated in vacuo and the resulting oil distilled bulb-to-bulb taking a middle cut at 120°-140° at 0.17 mm Hg.
