A solution of the 3-chloro-4-fluoronitrobenzene (50 g, 0.29 mol, 1.00 equiv) in acetonitrile (250 ml) was added and the mixture was stirred at 40° C. for 14 hours and then cooled to room temperature. Water (1000 ml) was added and the precipitated solids were filtered and washed with water and dried to give product 52.5 g. MS (ESI) m/z: 265 (M+1).
