Ammonium formate → 7-(3-(trifluoromethyl)pyridin-2-yl)-N-(5-(trifluoromethyl)pyridin-2-yl)-1,8-naphthyridin-4-amine

Participants

Reaction Steps

Stir a mixture of 2-chloro-7-[3-(trifluoromethyl)pyridin-2-yl]-N-[5-(trifluoromethyl) pyridin-2-yl]-[1,8]naphthyridin-4-amine (40 mg), ammonium formate (31 mg), 10% palladium on carbon (10 mg) in methanol (2 mL) at 50° C. for 2 hours. Cool, filter through Celite and evaporate to dryness. Purify by preparative thin layer chromatography, eluting with dichloromethane/methanol/ammonium hydroxide mixture to give the title compound.
