Reaktionsschritte

A solution of 2-bromo-1-(2,4-difluorophenyl)ethanone (5.0 g, 21.3 mmol) and potassium thiocyanate (2.07 g, 21.3 mmol) in ethanol (50 ml) was stirred at 80° C. for 2 hours. After cooling to room temperature, water (70 ml) was poured to the reaction mixture. A crystal was collected by filtration and washed with 50% aqueous ethanol to give 3.39 g (74.7%) of the desired product as a solid.
