Participants

Reaction Steps

A mixture of tert-butyl (S)-1-(5-(3-fluoroisoquinolin-6-yl)-1,3,4-thiadiazol-2-ylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.047 g, 0.086 mmol) in TFA/DCM (1:1, 4.0 mL) was stirred at room temperature for 30 minutes. The solvent was evaporated to provide the product as an off-white solid (50.3 mg, 100%). LCMS (API-ES) m/z: 449 (M+H+); 1H NMR (400 MHz, DMSO-d6) δ ppm 3.05 (d, J=6.85 Hz, 2H), 3.54-3.65 (m, 2 H), 7.57 (d, J=8.02 Hz, 2 H), 7.72 (d, J=7.82 Hz, 3 H), 7.76 (s, 1 H), 8.03 (s, 3 H), 8.11 (dd, J=8.61, 1.57 Hz, 1 H), 8.28 (d, J=8.80 Hz, 1 H), 8.33-8.39 (m, 2 H).
