Reaction Steps

Into a 100-mL round bottom flask, was placed a solution of 2-amino-5-(piperidin-1-yl)-N-(1-(3-(trifluoromethyl)phenyl)-1H-1,2,4-triazol-3-yl)benzamide (150 mg, 0.35 mmol, 1.00 equiv) in dichloromethane (20 mL), and pyridine (83 mg, 1.05 mmol, 3.01 equiv). This was followed by dropwise addition of a solution of 3-(methyl(2-morpholinoethyl)carbamoyl)benzoyl chloride (130 mg, 0.42 mmol, 1.20 equiv) in dichloromethane (10 mL) with stirring at 0-5° C. The resulting solution was stirred for 3 h at room temperature. The resulting solution was diluted with 30 mL of dichloromethane. The resulting mixture was washed with 1×20 mL of NH4Cl and 2×20 mL of brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. The crude product (200 mg) was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 36.7 mg (15%) of a yellow solid. 1H-NMR (400 MHz, DMSO, ppm): δ 11.43-11.33(m, 2H), 9.70(s, 1H), 9.43(s, 1H), 8.77(s, 1H), 8.26-8.18 (m, 3H), 8.06-7.93 (m, 2H), 7.86-7.79(m, 2H), 7.68-7.62(m, 2H), 7.52(s, 1H), 7.30-7.28(d, J=6.9 Hz, 1H), 4.59-4.57(m, 1H), 4.18-3.83(m, 27H), 3.44(s, 3H), 3.27-3.26 (m, 5H), 3.18 (s, 3H), 2.96(s, 4H), 1.69(s, 4H), 1.59-1.52(m, 3H). MS (ES, m/z): 705 [M+H]+.
