Reaction Steps

To a solution of 2-nitro-benzenesulfonyl chloride (15 g, 0.068 mol) in 1,4-dioxane (100 mL) was added sodium carbonate (10.76 g, 0.1015 mol) and 2.000 M of dimethylamine in tetrahydrofuran (40.61 mL) at room temperature and the reaction mixture was stirred for 4 hours. The reaction mixture was partitioned between water and dichloromethane, and the aqueous layer was extracted once with dichloromethane. The combined organic extracts were dried (MgSO4), concentrated, and the solid residue was recrystallized from MeOH to afford N,N-dimethyl-2-nitro-benzenesulfonamide (14.7 g, 94%) as a white solid. LC/MS (ESI+): 230.92 (M+H).
