Reaction Steps

A 500 mL round bottom flask was charged with anhydrous DMF (100 mL), 2-bromothiophenol (10.0 g, 52.88 mmol), potassium carbonate (11.0 g, 79.59 mmol) and bromoacetaldehyde diethyl acetal (8.35 mL, 55.5 mmol). The reaction was stirred at room temperature for 5 hours. Water (50 mL) and ethyl acetate (100 mL) were then added with mixing. The layers were separated and the organic layer was washed with water (5×50 mL), dried over anhydrous sodium sulfate, filtered and concentrated under vacuum to provide 2-(2-bromophenylthio) acetaldehyde diethyl acetal (13.78 g, 85%).
