To a solution of 2-chloro-N-(2-chloro-4-cyano-6-fluorobenzoyl)-N-(2-chloro-3-fluoro-pyridin-4-yl)-4-cyano-6-fluoro-benzamide (0.865 g, 1.7 mmol) in MeOH (8.5 mL) and dioxane (8.5 mL) was added sodium hydroxide (0.102 g, 2.5 mmol). The resulting mixture stirred at room temperature for 2.5 hours and then concentrated under reduced pressure. The residue was partitioned between DCM and saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography eluting with 0-100% DCM in pentane to give the desired compound as an off-white solid (0.308 g, 55% yield). 1H NMR (300 MHz, CDCl3): δ 8.49-8.40 (m, 1H), 8.25 (d, J=5.4 Hz, 1H), 7.98 (br s, 1H), 7.64 (t, J=1.3 Hz, 1H), 7.47 (dd, J=7.9, 1.5 Hz, 1H). LCMS (Method D): RT=3.33 min, m/z: 328 [M+H+].
