1-(2-(2,3-dihydroxypropyl)-4-(trifluoromethyl)phenyl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.120 g, 0.182 mmol) was dissolved in DCM and TFA (0.1 ml, 1.298 mmol) was added. The reaction was stirred for 30 minutes at room temperature. The reaction was concentrated and the material was triturated in diethyl ether. The solids were filtered and washed with diethyl ether, then vacuum dried overnight to afford 1-(2-(2,3-dihydroxypropyl)-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide 2,2,2-trifluoroacetate as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm=12.89 (br. s., 1H), 8.71 (dd, J=2.0, 5.7 Hz, 1H), 8.59 (d, J=4.1 Hz, 1H), 8.25-8.12 (m, 1H), 7.94-7.83 (m, 2H), 7.76-7.64 (m, 2H), 7.51 (t, J=7.8 Hz, 1H), 7.28 (d, J=4.4 Hz, 1H), 6.88 (d, J=4.6 Hz, 1H), 4.04 (d, J=4.9 Hz, 1H), 3.53-3.44 (m, 1H), 3.29 (d, J=3.8 Hz, 1H), 3.10-3.02 (m, 1H), 3.02-2.94 (m, 1H), 2.87 (dd, J=4.0, 14.3 Hz, 1H), 2.37-2.29 (m, 1H). m/z (ESI) 510.2 (M+H)+.
