Procedure

Tert-butyl 3-iodopyrrolidine-1-carboxylate (0.029 g, 0.097 mmol) was added to a solution of 1-(4-bromo-5-fluoro-2-hydroxyphenyl)-N-(isoxazol-3-yl)-N-(4-methoxybenzyl)-2-oxo-1,2-dihydroquinoline-6-sulfonamide (0.058 g, 0.097 mmol) and cesium carbonate (0.063 g, 0.193 mmol) in acetonitrile (0.242 ml) and stirred for 48 hr. The reaction vessel was cooled to room temperature. The reaction mixture was then transferred to a sep. funnel and the aqueous layer was washed 3× with EtOAc. The organic layers were combined, dried with MgSO4, filtered and concentrated to an oil. The crude mixture was taken onward to the next step assuming quantitative yield. m/z (ESI) 670.9 (M+H)+.
