Reaction Conditions

Reaction Steps

Cesium carbonate (18.0 g, 55 mmol) and benzyl bromide (6.6 mL, 55 mmol) were added to a solution of N-(2-formylphenyl)methanesulfonamide (5.50 g, 27.6 mmol) in acetonitrile (120 mL). The reaction mixture was heated at 60° C. for 16 h and then cooled to ambient temperature. The mixture was diluted with EtOAc (200 mL) and filtered. The filtration cake was washed with EtOAc (200 mL) and the combined organics were concentrated. The residue was purified by flash column chromatography on silica gel (EtOAc/hexane=1:5) to afford 1-benzyl-1H-benzo[c][1,2]thiazine 2,2-dioxide (6.5 g, 87% yield) as a colorless oil.
