2-Bromo-3-phenyl-butyrophenone (0.02 mol), 1,2,4-triazole (0.02 mol) and potassium carbonate (0.04 mol) were refluxed in methyl ethyl ketone (100 ml) for 36 hours. After cooling to room temperature, the solution was filtered and the solvent removed in vacuo. Recrystallisation of the residue from ethanol/petroleum ether (60°-80°) gave the title compound as a colourless solid, m.p. 166°-8°.
