실험 절차

A mixture of methyl 4-bromo-2-(bromomethyl)benzoate (12 g) and sodium thiomethoxide (2.5 g) in toluene was stirred at 100° C. for 2 hours. The mixture was then cooled, poured into water and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried (anhydrous sodium sulphate) and evaporated to afford a brown oil which was purified by column chromatography on silica gel giving methyl 4-bromo-2-(methylsulphenylmethyl)benzoate (4.1 g) as white crystals, m.p. 79.3° C.
