Reaction Steps

To a suspension of 4-(4-fluorophenylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]thiazine-6-carbonyl chloride (0.027 g, 72.6 μmol) in DCE (1 mL) was added morpholine (15.97 μL, 182 μmol) and pyridine (350 μL). The reaction was heated to 70° C. and stirred at that temperature for 16 hours. LCMS analysis of the reaction mixture indicated complete consumption of starting material. The resulting solid was purified by flash column chromatography using a gradient elution of hexanes with 0-60% EtOAc to provide (4-(4-fluorophenylsulfonyl)-3,4-dihydro-2H-benzo[b][1,4]thiazin-6-yl)(morpholino)methanone (21.8 mg, 49.3 μmol, 88% yield for 2 steps) as off-white solid. LCMS (+ESI) m/z=423.5 [M+H]−.
