Dioxane (2.63 mL) and Water (0.875 mL) were added, the vial was flushed with argon and sealed, and heated in a microwave reactor at 90° C. for 30 minutes. The reaction was diluted with ethyl acetate and washed with water. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were dried with sodium sulfate, filtered, and concentrated. The material was purified via silica gel column chromatography (12 g, gradient elution 0 to 50% EtOAc:Heptane) to afford N-(2,4-dimethoxybenzyl)-1-(2-fluoro-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (0.271 g, 0.449 mmol, 85% yield) as a white solid. N-(2,4-dimethoxybenzyl)-1-(2-fluoro-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide (35 mg, 0.058 mmol) was dissolved in 1 mL of 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, dissolved in methanol, and passed through an SCX ion exchange column (pre-wetted with methanol). The column was flushed several times with methanol, then the product was liberated by flushing the column several times with 2.0 M ammonia in methanol. The product-containing filtrate was concentrated to afford 1-(2-fluoro-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)isoquinoline-6-sulfonamide as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm=12.92 (br. s., 1H), 8.77 (d, J=5.7 Hz, 1H), 8.62 (d, J=1.6 Hz, 1H), 8.24 (d, J=5.6 Hz, 1H), 7.99-7.91 (m, 2H), 7.89-7.77 (m, 3H), 7.27 (d, J=4.6 Hz, 1H), 6.87 (d, J=4.6 Hz, 1H). m/z (ESI) 454.1 (M+H)+.

Procedure:
To a suspension of 2,3-dichloro-isonicotinic acid (7.7 g, 40 mmol) in dichloromethane (45 mL) were added DMF (0.1 mL) and oxalyl chloride (17.5 mL, 200 mmol). The reaction mixture was stirred at room temperature for 18 hours and then concentrated under reduced pressure. The resultant residue was azeotroped with toluene, then cooled to 0° C. and dissolved in methanol (135 mL). The mixture was allowed to warm to room temperature and then concentrated under reduced pressure to give a residue. The residue was dissolved in ethyl acetate and the resulting solution was washed with a saturated solution of sodium hydrogen carbonate, water and brine, dried (Na2SO4), filtered and concentrated to give the title compound as a colourless oil that crystallised on standing (7.9 g, 96%). 1H NMR (CDCl3, 400MHz) 8.38 (d, J=5.0 Hz, 1H), 7.52 (d, J=5.0 Hz, 1H), 3.99 (s, 3H).
