Procedure

To a stirred solution of 7-fluoro-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazine-6-carbonitrile (CAS Reg. No. [151982-49-9], 4.71 g) in N,N-dimethylacetamide (108 ml) were added KOtBu (3.08 g) and methyl iodide (3.83 g). The mixture was stirred at room temperature for 3.5 h. Ice water was added. The suspension was filtered and the solid was washed with water and dried to give the title compound (4.07 g) as an off-white solid.
