Reaction Steps

To a solution of 5-bromo-6-methylpyridin-2(1H)-one (164 mg, 0.872 mmol) and iodomethane (0.065 mL, 1.047 mmol) in DMSO (3 mL) was added K2CO3 (145 mg, 1.047 mmol). The mixture was stirred at 60° C. overnight, filtered, and purified via preparative HPLC, eluting with a gradient of 20-70% ACN (containing 0.035% TFA) in H2O (containing 0.05% TFA) to give the title compound.
