Reaction Steps

To a slurry of 3-(5-fluoro-2-methylphenyl)-7-(cyclopropanecarboxamido)-2,6-naphthyridine 2-oxide (50 mg, 0.1 mmol) in acetonitrile (0.4 mL) was added N,N-diisopropylethylamine (0.05 mL, 0.3 mmol), followed by trimethylsilyl cyanide (0.06 mL, 0.44 mmol). The mixture was heated at 100° C. for 2 hours. The cooled reaction mixture was diluted with ethyl acetate (50 mL) and washed with water (20 mL). The organic layer was separated, dried over sodium sulfate, filtered, and evaporated in vacuo to afford a residue that was purified by reverse phase HPLC (5-85% acetonitrile in water with 0.1% formic acid over 14 min) to afford the title compound as a white solid (10 mg, 20%). 1H NMR (400 MHz, DMSO) δ 11.47 (s, 1H), 9.52 (s, 1H), 8.84 (s, 1H), 8.56 (s, 1H), 7.48-7.35 (m, 2H), 7.26 (td, J=8.5, 2.8 Hz, 1H), 2.37 (s, 3H), 2.13 (m, 1H), 0.99-0.83 (m, 4H). LCMS (Method E): RT=5.495 min, M+H+=347.1.
