Reaction Steps

To a solution of 4-fluoro-5-((2-fluoro-4-iodophenyl)amino)-N-(2-(vinyloxy)ethoxy)benzo[d][1,2,3]thiadiazole-6-carboxamide (190 mg, 0.37 mmol) in CH2Cl2 (10 mL) was added 1.0 N HCl (aq., 1.5 mL, 1.5 mmol). After stirring for 1 h, the reaction mixture was neutralized with saturated NaHCO3 (aq.). The aqueous layer was washed with CH2Cl2 (10 mL×2). The combined organic layer was washed with water (30 mL) and brine (30 mL), dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by column chromatography on silica gel (CH2Cl2/MeOH, 20:1, v/v) and gave the desired product as a yellow solid (154 mg, 84.6% yield). 1H NMR (400 MHz, DMSO-d6): δ 11.88 (s, 1H), 8.65 (s, 1H), 8.52 (s, 1H), 7.36 (d, 1H), 7.25 (d, 1H), 6.42 (d, 1H), 4.69 (m, 1H), 4.05 (m, 2H), 3.80 (m, 2H). MS APCI (+) m/z: m/z 493.2, [M+H].
