Procedure

A three-neck round bottom flask was charged with 3-chloro-thiophenol (20.0 g, 0.138 mol) and potassium carbonate (21 g, 0.15 mol) in acetone (220 ml) and treated with a dropwise addition of bromoacetaldehyde diethyl acetal. After stirring for 17 hours at 23° C., the slurry was filtered through a small plug of celite, the filtrate evaporated under reduced pressure and the residue diluted with diethyl ether and water. The organics were washed with brine, dried over sodium sulfate, and evaporated to a rust-colored oil weighing 35.1 g (97%). FDMS m/e=260 (M+).
