Isopropanol → 4-Isopropoxy-N-methyl-3-nitrobenzenesulfonamide

Participants

Reaction Steps

NaH (0.440 g, 11 mmol) was added to 20 mL of isopropanol and the resulting mixture stirred at room temperature. After 30 minutes, 4-fluoro-N-methyl-3-nitrobenzenesulfonamide (2.34 g, 10 mmol) was added. The reaction mixture was then stirred at room temperature overnight. The mixture was poured into EtOAc and water. The organic phase was separated, dried over Na2SO4, and concentrated in vacuo to give the crude product. Purification via column chromatography (1:1 petroleum ether/ethyl acetate) afforded N-methyl-4-[(1-methylethyl)oxy]-3-nitrobenzenesulfonamide (1.6 g, 58% yield) as a yellow solid. MS (m/z) 274.7 (M+H+)
