Versuchsvorschrift

A solution of 8.0 g (42 mmol) of 3-bromothiophenol was treated with 7.1 g (47 mmol) of methyl bromoacetate and potassium carbonate. The resulting suspension was stirred at reflux for 24 hrs, cooled to RT and neutralized with a saturated aqueous solution of NH4Cl. Diethylether was added, the phases were separated and the aqueous one was extracted twice with diethylether. The combined organic phases were dried over Na2SO4, filtered and evaporated to give 12.1 g (99%) of (3-bromo-phenylsulfanyl)-acetic acid methyl ester as a light yellow oil, MS: 279 (MNH4+, 1Br).
