Benzenesulfonyl chloride → N'-t-butyl-N-benzoyl-N'-benzenesulfonylhydrazine

Participants

Reaction Steps

N-benzoyl-N'-t-butyl hydrazine (0.8 g) was stirred in pyridine (2 ml) at room temperature. Benzenesulfonyl chloride (0.8 g) was added slowly dropwise, stirred about 1 hour, diluted with diethyl ether (10 ml) and washed several times with a 10% HCl solution and then water. The organic layer was dried over magnesium sulfate. The mixture was filtered and the solvent rotavapped off to afford a white solid in good yield.
