Procedure
To a solution of N-(1-((4-amino-2,2-dioxido-1H-benzo[c][1,2,6]thiadiazin-5-yl)oxy)-2-methylpropan-2-yl)-2-cyanoisonicotinamide (300 mg, 724 umol) in ethanol (20 mL) at room temperature, was added a solution of sodium hydroxide (275 mg, 7.06 mmol) in water (6 mL). The reaction was microwaved at 80° C. for five minutes, and upon completion was cooled 0° C., neutralized with 1N HCl, concentrated and purified by flash chromatography (1/9 methanol/dichloromethane). The purified product was washed with hot ethanol and the solid was collected by vacuum filtration and dried under vacuum at 50° C. to yield N4-(1-((4-amino-2,2-dioxido-1H-benzo[c][1,2,6]thiadiazin-5-yl)oxy)-2-methylpropan-2-yl)pyridine-2,4-dicarboxamide (95 mg, 29%) as a white solid. 1H NMR (DMSO-d6, 400 MHz): δ 1.50 (s, 6 H), 4.38 (s, 2H), 6.62 (d, J=0.8 Hz, 1H), 6.80 (d, J=8.4 Hz, 1 H), 7.47 (t, J=8.4 Hz, 1H), 7.75 (s, 1H), 7.80 (s, 1H), 7.86 (dd, J=5.2 Hz, 1H), 8.19 (s, 1H), 8.35 (s, 1H), 8.39 (s, 1H), 8.69 (s, 1H), 8.73 (dd, J=4.8 Hz, 1H), 10.99 (s, 1H). MS 433 (MH+).
