実験手順

5-(4-Bromophenoxy)-2-(methylthio)phenol (0.05 mole), potassium carbonate (0.2 mole), methyl 2-bromoacetate (0.08 mole) and dimethylsulfoxide (200 ml) are charged into a 500 ml glass reaction flask equipped with a mechanical stirrer. The reaction mixture is stirred at room temperature for a period of about 8 hours. After this time the mixture is poured into 500 ml of water. The resulting mixture is extracted three times with 100 ml portions of methylene chloride. The extracts are then combined, washed with water and therafter dried. The dried solution is then stripped of solvent under reduced pressure to leave a residue. The residue is subjected to chromatography using a clay column and hexane/ethyl acetate mixture as the eluant. The fractions containing the product are combined and stripped of solvent to yield the desired product methyl 2-[5-(4-bromophenoxy)-2-methylthiophenoxy]acetate as the residue.
