Participants

Reaction Steps

To a solution of 1-(5-amino-2-chloropyridin-4-yl)ethanone (1.0 equiv.) in pyridine (0.26 M) was added 4-nitrophenylsulfonylchloride (3.0 equiv.). The resulting amber solution was stirred at rt for 18 hours, at which time it was poured onto ice. The resulting solid was filtered, rinsed with H2O and pumped on yielding N-(4-acetyl-6-chloropyridin-3-yl)-4-nitro-N-(4-nitrophenylsulfonyl)benzenesulfonamide (88%). LC Rt=4.77 min.
