Procedure

To a stirred solution of KOH (5.81 g) in DMSO (15 mL) was added imidazole (5.0 g, 73.4 mmol). The mixture was stirred for 1 hour, then 2-fluorobenzonitrile (8.76 mL) in DMSO (10 mL) was added dropwise over 20 minutes. The reaction mixture was stirred at room temperature overnight and the product was collected by filtration and washed with water to afford 10.91 g of 2-(1-imidazolyl)benzonitrile as a white solid.
