Procedure

To a slurry of N-(7-(5-fluoro-2-methylphenyl)-5-(hydroxymethyl)-2,6-naphthyridin-3-yl)cyclopropanecarboxamide (60 mg, 0.1 mmol), in dichloromethane (0.7 mL) cooled at −15° C. was added bis(2-methoxyethyl)aminosulfur trifluoride (0.045 mL, 0.2 mmol). After 15 minutes at this temperature, the reaction mixture was diluted with dichlormethane (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 an off-white solid (50 mg, 50%). 1H NMR (400 MHz, DMSO) δ 11.23 (s, 1H), 9.38 (s, 1H), 8.85 (s, 1H), 8.21 (s, 1H), 7.47-7.33 (m, 2H), 7.21 (m, 1H), 5.99 (s, 1H), 5.88 (s, 1H), 2.37 (s, 3H), 2.11 (m, 1H), 0.89 (m, 4H). LCMS (Method G): RT=14.65 min, M+H+=354.4.
