Reaction Steps

To a solution of sodium methoxide (0.023 g, 0.43 mmol) in anhydrous methanol (3 mL) was added 2-chloro-N-(2,4-difluorophenyl)-4-iodonicotinamide (0.17 g, 0.43 mmol). The mixture was heated at 60° C. for 12 hours then allowed to cool to ambient temperature. Concentration of the reaction mixture resulted in a residue that was triturated with methanol and water. Isolation by vacuum filtration afforded the desired compound (0.035 g) as an off-white solid. The filtrate was concentrated in vacuo to a residue that was purified by flash column chromatography (SiO2, eluting with 25-100% EtOAc in hexane) to afford an additional amount desired compound (0.049 g, overall yield 65%) that was spectroscopically consistant with the initially isolated material. 1H NMR (DMSO-d6) δ 10.48 (s, 1H), 8.38 (d, 1H, J=5.8 Hz), 7.85-7.96 (m, 1H), 7.33-7.40 (m, 1H), 7.27 (d, 1H, J=5.8 Hz), 7.05-7.20 (m, 1H), 3.92 (s, 3H); MS(ESI+) m/z 299 (M+H)+.
