실험 절차

To a mixture of (S)—N-(3-(5-(2-(2-aminopropylamino)pyrimidin-4-yl)-2-cyclopropyl-1H-imidazol-4-yl)-2-chlorophenyl)propane-1-sulfonamide in THF-water (1:1, 2 mL) at 0° C. was added solid NaHCO3 (137 mg, 1.6 mmol) and the resulting mixture was stirred for 5 minutes. Methyl chloroformate (14 μL, 0.18 mmol) was added and the reaction mixture was stirred at 0° C. for 15 minutes. The reaction was diluted with water and extracted with EtOAc (2×). The combined organic portions were washed with water, brine, dried (Na2SO4), and concentrated. The resulting residue was dissolved in DMSO and purified by reverse phase HPLC. Product fractions were combined and lyophilized to give (S)-methyl 1-(4-(4-(2-chloro-3-(propylsulfonamido)phenyl)-2-cyclopropyl-1H-imidazol-5-yl)pyrimidin-2-ylamino)propan-2-ylcarbamate (19.9 mg) as the TFA salt (4A-3): LCMS (m/z) 548.0 (MH+), tR=0.61 minute, 1H NMR (400 MHz, CD3OD) δ 1.04 (t, J=7.4 Hz, 3H) 1.14 (d, J=6.6 Hz, 3H) 1.27 (t, J=4.5 Hz, 2H) 1.34-1.44 (m, 2H) 1.80-1.95 (m, 2H) 3.14-3.21 (m, 2H) 3.67 (br s, 3H) 3.97 (br s, 1H) 6.40 (br s, 1H) 7.45 (d, 7.0 Hz, 1H) 7.54 (m, 1H) 7.84 (d, J=7.4 Hz, 1H) 8.13 (d, J=5.1 Hz, 1H).
