Reaction Steps

2-Chloro-5-nitro-3-(trifluoromethyl)pyridine 4 (1.57 g, 6.93 mmol) is dissolved in tetrahydrofuran (THF) (10 ml) and added to a suspension of Raney-Ni (200 mg) in THF (20 ml). Hydrogen gas is slowly bubbled through the stirred solution for 24 hours using a balloon. The mixture is filtered through Celite® (available from World Minerals, Inc., Lompoc, Calif.) and the solvent is removed under reduced pressure to obtain 6-chloro-5-(trifluoromethyl)pyridin-3-amine 5.
