Versuchsvorschrift
A mixture of N,N-diallyl-4-chloropyridine-3-sulfonamide (1.5 g, 5.5 mmol), lithium iodide (0.74 g, 5.5 mmol) and ammonia (7 M in methanol, 14 mL, 5.5 mmol) under an atmosphere of argon was heated at 120° C. for 2 h in a microwave reactor. Silica was added and the solvent was evaporated. Purification by column chromatography, using chloroform/methanol (95:5) as the eluent, gave the title compound in 59% yield.
