Reaction Steps

To a solution of 2-(4-bromo-3-nitro-phenyl)-3-(trifluoromethyl)-pyridine (0.55 mmol) in DMA (4 mL) add CuCN (0.60 mmol). Stir the mixture 4 hours at 110° C. Cool to room temperature, dilute with 20 ml of EtOAc, and filter through celite pad. Wash the filtrated with brine, dry over Na2SO4, concentrate under vacuum, and purify by flash chromatography (1:1 hexanes/EtOAc) to give 2-nitro-4-(3-trifluoromethyl-pyridin-2-yl)-benzonitrile.
