Reaction Steps

A RBF was charged with perfluorophenyl 1-(5,6-dichloro-2-methoxypyridin-3-yl)-2-oxo-1,2-dihydroquinoline-6-sulfonate (1.0 g, 1.763 mmol), isoxazol-3-amine (0.143 ml, 1.939 mmol), and THF (8.81 ml) to give a clear solution. The flask was cooled to 0° C. for 10 min, then lithium bis(trimethylsilyl)amide (1M in THF) (3.88 ml, 3.88 mmol) was added dropwise. The reaction was stirred for 30 minutes. The reaction was diluted with 1N aq. HCl and EtOAc. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were washed with 1N aq. HCl, washed with brine, dried with sodium sulfate, filtered, and concentrated to afford crude 1-(5,6-dichloro-2-methoxypyridin-3-yl)-N-(isoxazol-3-yl)-2-oxo-1,2-dihydroquinoline-6-sulfonamide (1.10 g, 2.354 mmol, 100% yield) as an orange solid. m/z (ESI) 467.0 (M+H)+.
