実験手順
tert-Butyl (S)-1-(5-(4-chlorothieno[2,3-c]pyridin-2-yl)-1,3,4-thiadiazol-2-ylamino)-3-(3-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.070 g, 0.12 mmol) was treated with 1 mL TFA in 1 mL DCM for 30 minutes. After removing the solvent, the residue was mixed with 10 mL 2M ammonia in MeOH. The solvent was removed again and the remaining residue was subjected to a silica gel flash chromatography separation using 3.5% 2M ammonia MeOH solution in DCM as the eluant. An-off white solid was obtained as the pure product (0.03 g, y=52%). LCMS (API-ES) m/z (%): 470.1 (100%, M++H); 1H NMR (300 MHz, CDCL3) δ ppm 1.48-1.82 (b, 3H) 2.72 (dd, J=13.56, 8.48 Hz, 1H) 3.00 (dd, J=13.66, 4.99 Hz, 1H) 3.26-3.35 (m, 1H) 3.40-3.50 (m, 1H) 3.61 (dd, J=12.72, 3.67 Hz, 1H) 7.41-7.56 (m, 6H) 8.46 (s, 1H) 8.95 (s, 1H).
