Reaction Steps

4-Nitrophenylsulfonyl chloride (3.0 g, 13.5 mmol) was dissolved in THF and a catalytic amount of 4-dimethylaminopyridine and 1-butylamine (4.0 mL, 41 mmol) was added and the mixture was refluxed for 16 hours. The mixture was concentrated in vacuo and the residue was dissolved in ethyl acetate (100 mL) and washed with water (50 mL) and a 10% aqueous solution of sodium hydrogen carbonate (50 mL). The organic phase was dried (MgSO4) and concentrated in vacuo to afford 3.01 g (86%) of N-butyl-4-nitrobenzenesulfonamide as a solid.
