Methanesulfonyl chloride → HCID 1485426, compound

Participants

Reaction Steps

To a solution of (3-quinoxalin-2-ylphenyl)amine (2.21 g, 0.01 mol) in pyridine (10 mL), methanesulfonyl chloride (0.77 mL, 0.01 mol) was added dropwise at 0-5° C. with stirring. The reaction mixture was stirred overnight at room temperature, and then diluted with water. The resulting solid was filtered and dried to afford N-[3-(quinoxalin-2-yl)phenyl]methanesulfonamide (2.6 g, 87% yield). LCMS calculated for C15H13N3O2S (M+H): 300.07. found 300. 1H-NMR (DMSO-d6, 250 Mhz) δH: 10.01 (1H, br. s), 9.50 (1H, s), 8.20-8.00 (4H, m), 7.95-7.70 (2H, m), 7.60-7.52 (1H, m), 7.48-7.40 (1H, m), 3.04 (3H, s).
