Participants

Reaction Steps

A 60% suspension of NaH (0.47 g, 11.75 mmol) was added to a solution of N-(3-nitrophenyl)benzenesulfonamide (2.56 g, 9.20 mmol) and iodomethane (2.61 g, 18.4 mmol) in DMF (50 mL) at room temperature. The yellow solution changed to a bright brown color. After 1.5 h at room temperature, the reaction mixture was quenched with careful addition of water (100 mL) and extracted with EtOAc (2×50 mL). The combined extracts were washed with saturated NH4Cl, brine, dried (MgSO4) and concentrated to give N-methyl-N-(3-nitrophenyl)benzenesulfonamide (3.09 g). LCMS: (M+MeCN+Na)+=356.0. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.16 (1H, ddd, J=8.03, 2.26, 1.25 Hz), 7.94 (1H, t, J=2.13 Hz), 7.70-7.76 (1H, m), 7.66 (1H, t, J=8.03 Hz), 7.57-7.62 (3H, m), 7.52-7.56 (2H, m), 3.21 (3H, s).
