To a solution of the tert-butyl 4-(5-(((3-fluoro-2′-(trifluoromethyl)-[2,4′-bipyridin]-5-yl)methyl)carbamoyl)pyridin-2-yl)piperazine-1-carboxylate 46-2 in DCM (3.0 mL) was added trifluoroacetic acid (1.0 mL) and the solution was stirred overnight. The reaction mixture was concentrated, redistributed between ethyl acetate and 5% Na2CO3 solution and the organic phase dried over Na2SO4. Concentration with rotavap gave crude N-((3-fluoro-2′-(trifluoromethyl)-[2,4′-bipyridin]-5-yl)methyl)-6-(piperazin-1-yl)nicotinamide 46-3.
