N-bromobutanimide → 2-(2-Bromothiophen-3-yl)ethan-1-ol

Participants

Reaction Steps

To a stirred solution of 2-(3-thienyl)ethanol (25.0 g, 0.195 mol) in carbon tetrachloride (250 ml) was added N-bromosuccinimide (34.7 g, 0.195 mol) in several portions over a 15 minute period. The mixture was stirred at room temperature for one hour. The succinimide was removed by filtration and the filtrate was concentrated in vacuo at room temperature to give the product as a viscous amber oil (40.2 g) (99%). TLC indicated that the product was pure and mass spectral analysis showed a molecular ion at M/Z 206. NMR supported the structure.
