Reaction Steps

A RBF was charged with perfluorophenyl 1-(4-bromo-2-methoxy-5-methylphenyl)-2-oxo-1,2-dihydroquinoline-6-sulfonate (5.00 g, 8.47 mmol), and THF (85 ml). To this, was added pyrimidin-2-amine (1.208 g, 12.71 mmol) and the reaction was cooled to 0° C. Lithium bis(trimethylsilyl)amide, 1.0 M solution in tetrahydrofuran (18.63 ml, 18.63 mmol) was added dropwise and allowed to stir at 0° C. After 1 hour, the mixture was diluted with 1N aq. HCl (10 mL) and EtOAc. The layers were separated, and the aq. layer was extracted with EtOAc (2×). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated. The residue was purified by chromatography on silica gel (40 g Redi-Sep Gold column, 10-50% of a 3:1 EtOAc/EtOH solution in heptane) to give 1-(4-bromo-2-methoxy-5-methylphenyl)-2-oxo-N-(pyrimidin-2-yl)-1,2-dihydroquinoline-6-sulfonamide (3.54 g, 7.06 mmol, 83% yield) as an off white solid. m/z (ESI) 502.8 (M+H)+.
