Into a 50-mL round bottom flask, was placed a solution of 2-(2-nitro-5-(piperidin-1-yl)phenyl)isonicotinic acid (1 g, 3.06 mmol, 1.00 equiv) in dichloromethane (20 mL), EDC.HCl (970 mg, 5.05 mmol, 1.65 equiv), 4-dimethylaminopyridine (620 mg, 5.08 mmol, 1.66 equiv), and (3-(trifluoromethyl)phenyl)methanamine (590 mg, 3.37 mmol, 1.10 equiv). The resulting solution was stirred overnight at 25° C. in an oil bath. The reaction progress was monitored by LCMS. The mixture was concentrated under vacuum. The residue was applied onto a silica gel column and eluted with petroleum ether/ethyl acetate (10:1˜3:1). This resulted in 800 mg (51%) of N-(3-(trifluoromethyl)benzyl)-2-(2-nitro-5-(piperidin-1-yl)phenyl)isonicotinamide as a yellow solid.
