Reaction Conditions

Reaction Steps

Dissolve 6-amino-3′-trifluoromethyl-[2,2′]bipyridinyl-5-carbonitrile (1.0 g, 7.6 mmol) in 12 N HCl (20 mL) and cool to 0° C. Add NaNO2 (731 mg, 10.6 mmol) in portions over the course of 15 minutes. Allow the mixture to stir for 1 hour at 0° C. Add CuCl (2.24 g, 22.7 mmol), allow the mixture to warm to room temperature and stir for 1 hour. Pour the mixture onto ice water (100 mL) and extract with EtOAc (3×100 mL);. Dry the combined organic extracts over Na2SO4 and remove the solvent under reduced pressure. Purify the crude product by silica gel chromatography eluting with EtOAc/hexane (1:1) to yield the title compound. MS 284.04 (M+1).
