Reaction Steps

To a solution of 6-bromo-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (185 mg, 0.722 mmol) in DMF (3 mL) at 0° C. was added NaH (43.3 mg, 1.08 mmol, 60%), and the reaction was stirred for 5 minutes. Iodomethane (205 mg, 1.45 mmol) was added the reaction was stirred at room temperature for 60 minutes. Water, EtOAc, and brine were added, the layers were separated and the organic layer was washed with brine. The organics were dried over MgSO4, filtered and concentrated. The residue was purified by flash chromatography (10-35% EtOAc in hexanes) to afford 6-bromo-2,2,4-trimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one 7.31 (132 mg). LCMS-ESI+ (m/z): [M+H]+ calcd for C11H13BrNO2: 270.0; found: 270.0.
