N'-t-butyl-N'-benzoylhydrazine (0.4 g) was stirred in pyridine (3 ml) at room temperature. Benzenesulfonyl chloride (0.5 g) was added slowly, dropwise and stirred for 2 hours, diluted with diethyl ether (20 ml) and washed several times with a 10% HCl solution and then water. The organic layer was dried over magnesium sulfate, filtered and the solvent rotavapped off to afford a white solid in good yield.
