Reaction Steps

Into a 50-mL round-bottom flask, was placed a solution of 2-nitro-5-(piperidin-1-yl)benzoic acid (1.096 g, 4.38 mmol, 1.50 equiv) in dichloromethane (20 mL), 2-phenylpyrimidin-5-amine (500 mg, 2.92 mmol, 1.00 equiv), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (838 mg, 4.39 mmol, 1.50 equiv), and 4-dimethylaminopyridine (713 mg, 5.84 mmol, 2.00 equiv). The resulting solution was stirred overnight at 25° C. The reaction was diluted with 100 mL of water and the resulting mixture was extracted with 3×50 mL of dichloromethane. The organic layers were combined, washed with 1×100 mL of brine, dried over sodium sulfate, and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with PE:EA:CH2Cl2 (20:1:0-3:1:1). The product was obtained as 150 mg (11%) of a yellow solid.
