Participants

Reaction Steps

A solution of 5-acetylthiophene-3-carboxamide (0.5 g) in chloroform at 50° was treated with hydrogen bromide in acetic acid (4 drops) and then bromine (0.15 ml) in chloroform (10 ml) dropwise over 30 min. The resulting pale yellow solution was washed with water (2×100 ml), dried and evaporated to small volume to deposit the title compound as a white solid (0.55 g) which recrystallised from water, m.p. 150°-157° (d).
