Into a 250-mL round-bottom flask, was placed a solution of 1-(3-(trifluoromethyl)phenyl)-1H-imidazol-4-amine (1.2 g, 4.49 mmol, 1.00 equiv, 85%) in dichloromethane (30 mL), 2-nitro-5-(piperidin-1-yl)benzoic acid (1.32 g, 5.07 mmol, 1.00 equiv, 96%), EDC.HCl (2 g, 10.42 mmol, 2.00 equiv), and 4-dimethylaminopyridine (1.29 g, 10.57 mmol, 2.00 equiv). The resulting solution was stirred overnight at 28° C. The resulting solution was diluted with 200 mL of dichloromethane. The resulting mixture was washed with 1×30 mL of 10% sodium bicarbonate and 1×30 mL of brine, dried over sodium sulfate, and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:1) to give 600 mg (22%) of product as brown oil.
