Reaction Steps

To the solution of 5-bromo-7-methylquinolin-6-ol (238 mg, 1.0 mmol) in dichloromethane (10 mL) and pyridine (2 mL) was added Tf2O (0.34 mL, 2.0 mmol) at −30° C. The mixture was stirred and warmed to 0° C. over a period of 2 hours. The reaction was quenched with slow addition of NaHCO3 solution. The mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated to give 5-bromo-7-methylquinolin-6-yl trifluoromethanesulfonate. LCMS-ESI+ (m/z): 369.9, 371.9 (M+H)+.
