Methyl iodide → N-Methyl-N-(2-(morpholine-4-carbonyl)-5-nitrophenyl)methanesulfonamide

Participants

Reaction Steps

Iodomethane (0.040 mL, 0.643 mmol) was added to a solution of N-(2-(morpholine-4-carbonyl)-5-nitrophenyl)methanesulfonamide (108 mg, 0.321 mmol) and 60% suspension of NaH (16.5 mg, 0.413 mmol) in DMF (0.5 mL) at room temperature. After 1.5 h at room temperature, the mixture was carefully quenched with water (10 mL) and extracted with EtOAc (3×4 mL). The combined EtOAc phase was concentrated, purified by silica gel chromatography, and eluted with 10-100% EtOAc in hexanes to give a yellow oil (101.3 mg, 92% yield). LCMS: (M+H)+=344.0. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.39 (1H, d, J=2.26 Hz), 8.27 (1H, dd, J=8.53, 2.26 Hz), 7.71 (1H, d, J=8.53 Hz), 3.69-3.78 (2H, m), 3.47-3.61 (4H, m), 3.10-3.30 (2H, m), 3.21 (3H, s), 3.17 (3H, s).
