Procedure

To a solution of methyl magnesium iodide prepared from magnesium (0.72g.; 0.03 mole) and methyl iodide (1.42g.; 0.01 mole) in ether (20ml) using standard methods, 4-bromo-phenylbenzyl ether in ether (20ml) was added dropwise with stirring then stirred until reaction was complete (1hr.). Ethyl chloroformate (3.24g.; 0.03 mole) in dry ether (20ml) was then added to the reaction mixture which was then boiled under reflux for 2 hrs. After cooling the reaction mixture was allowed to stand at room temperature for two days then worked up by the addition of water (40ml) and dilute hydrochloric acid (20ml). Separation of the ether layer followed by drying (anhyd. MgSO4), yielded 4-ethoxycarbonylphenoxy phenyl methane, m.p. 45° C.
