Participants

Reaction Steps

Into a 100-mL round bottom flask, was placed a solution of 6-(2-amino-5-(piperidin-1-yl)phenyl)-N-(3-(trifluoromethyl)benzyl)pyrimidin-4-amine (300 mg, 0.70 mmol, 1.00 equiv) in N,N-dimethylformamide (6 mL). This was followed by the addition of 3-(2-(2-hydroxyethoxy)ethylcarbamoyl)benzoic acid (302.2 mg, 1.19 mmol, 1.70 equiv) at room temperature. To this was added triethylamine (156 mg, 1.54 mmol, 2.20 equiv). To the mixture was added EDC.HCl (148.2 mg, 0.78 mmol, 1.10 equiv) at room temperature, followed by HOBT (104.4 mg, 0.77 mmol, 1.10 equiv) at room temperature. The resulting solution was stirred overnight at room temperature. The resulting mixture was concentrated under vacuum. The crude product was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. The product was obtained as 83.6 mg (15%) of a yellow solid. 1H-NMR (300 MHz, CD3OD, ppm): δ 8.76 (s, 1H), 8.40 (s, 1H), 8.039 (t, J=8.1 Hz, 2H), 7.74 (s, 1H), 7.63˜7.57 (m, 3H), 7.53˜7.50 (m, 2H), 7.47˜7.40 (m, 2H), 6.93 (s, 1H), 4.81 (s, 2H), 3.71˜3.58 (m, 8H), 3.43˜3.39 (m, 4H), 1.84˜1.81 (m, 6H). MS (ES, m/z): 663 [M+H]+.
