Procedure

To a mixture of (3-fluoro-2′-(trifluoromethyl)-[2,4′-bipyridin]-5-yl)methanamine 84-2 (53 mg, 0.195 mmol), 6-(4-(tert-butoxycarbonyl)piperazin-1-yl)nicotinic acid 46-1 (16 mg, 0.195 mmol), and HATU (81.5 mg, 0.214 mmol) were added N,N-diisopropylethylamine (DIEA, 52 μL, 0.298 mmol) and DMF (1.0 mL). The solution was stirred overnight at room temperature and was subjected to silica gel column chromatography with 1:1 ethyl acetate/hexanes as eluent to give tert-butyl 4-(5-(((3-fluoro-2′-(trifluoromethyl)-[2,4′-bipyridin]-5-yl)methyl)carbamoyl)pyridin-2-yl)piperazine-1-carboxylate 46-2.
