A solution of 2-bromo-1-(3-fluorophenyl)ethanone (1.00 g, 4.61 mmol) and potassium thiocyanate (448 mg, 4.61 mmol) in ethanol (10 ml) was stirred at 80° C. for 3 hours. After cooling to room temperature, water (12 ml) was poured into the reaction solution, and a crystal was separated by filtration, which was washed with 50% aqueous ethanol solution to give the desired product (668 mg, 74.3%) as a solid.
