Versuchsvorschrift

1-(2-bromo-4-(trifluoromethyl)phenyl)-N-(2,4-dimethoxybenzyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (see Example 70, step 3; 0.100 g, 0.150 mmol) was dissolved in DCM (1 mL). TFA (0.1 mL, 1.298 mmol) was added and the reaction was stirred for 30 minutes. The reaction was concentrated and the material was purified via silica gel column chromatography (12 g, gradient elution 0 to 10% MeOH:DCM) to afford 1-(2-bromo-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm=12.92 (br. s., 1H), 8.74 (d, J=5.8 Hz, 1H), 8.62 (d, J=1.4 Hz, 1H), 8.31-8.18 (m, 2H), 7.97 (d, J=7.9 Hz, 1H), 7.91 (dd, J=1.7, 8.9 Hz, 1H), 7.76 (d, J=7.9 Hz, 1H), 7.65 (d, J=8.8 Hz, 1H), 7.29 (d, J=4.3 Hz, 1H), 6.88 (d, J=4.5 Hz, 1H). m/z (ESI) 514.0 (M+H)+.
