実験手順: A solution of 6.0 g (23 mmol) of (3-bromo-phenylsulfanyl)-acetic acid methyl ester in 50 mL of dichloroethane was treated with 6.2 g (25 mmol) of 3-chloroperbenzoic acid. After 30 min of stirring another 6.2 g (25 mmol) of 3-chloroperbenzoic acid were added, the resulting suspension was stirred overnight at RT and then treated with a 0.5 M aqueous solution of sodium thiosulfate. The phases were separated and the aqueous one extracted twice with diethylether. The combined organic phases were washed with a ca. 1M aqueous NaHCO3 solution, dried over Na2SO4, filtered and evaporated to give 6.3 g (93%) of (3-bromo-benzenesulfonyl)-acetic acid methyl ester as a colorless oil, MS: 312 (MNH4+, 1Br). were added The phases were separated the aqueous one extracted twice with diethylether The combined organic phases were washed with a ca. 1M aqueous NaHCO3 solution dried over Na2SO4 filtered evaporated

実験手順: 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). at reflux for 24 hrs the phases were separated the aqueous one was extracted twice with diethylether The combined organic phases were dried over Na2SO4 filtered evaporated
