実験手順

(S)-tert-butyl 1-(N-(4-(3-hydroxy-3-methylbut-1-ynyl)-5-(isoquinolin-6-yl)thiazol-2-yl)-tert-butoxylcarbonylamino)-3-(4-(trifluoromethyl)phenyl)propan-2-ylcarbamate (0.010 g, 0.01 mmol) was taken up in 1 mL of DCM and TFA (0.2 mL) was added. After 1.5 hours, the solvent was removed under reduced pressure. The residue was loaded onto a Varian Mega Bond ELUT SCX column in MeOH, and eluted with 1M NH3 in MeOH to provide the free base. The solvent was removed under reduced pressure, and the residue was purified by flash chromatography on silica gel (pipette column, 2.5% to 10% MeOH/DCM) to afford 4-(2-((S)-2-amino-3-(4-(trifluoromethyl)phenyl)propylamino)-5-(isoquinolin-6-yl)thiazol-4-yl)-2-methylbut-3-yn-2-ol (0.002 g, 28% yield) as a yellow oil: LCMS (M+H) 511 calc. for C27H26F3N4OS 510.6. 1H NMR (400 MHz, CD3OD) δ ppm 9.17 (s, 1H) 8.41 (d, J=5.87 Hz, 1H) 8.28 (s, 1H) 8.07-8.13 (m, 2H) 7.79 (d, J=5.87 Hz, 1H) 7.62 (d, J=8.02 Hz, 2H) 7.47 (d, J=8.02 Hz, 2H), 3.47-3.25 (m, 3H) 2.95 (d, J=4.89 Hz, 1H) 2.73 (dd, J=13.40, 7.34 Hz, 1H) 1.60 (s, 6H).
