実験手順: 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. washed several times with a 10% HCl solution The organic layer was dried over magnesium sulfate filtered to afford a white solid in good yield

実験手順: N'-t-butyl-N'-benzoylhydrazine (1 g), benzoyl formic acid (0.7 g) and methanesulfonyl chloride (0.7 g) were stirred in toluene (30 ml) and saturated sodium bicarbonate (10 ml) at approximately 5° C. Triethylamine was added slowly, dropwise to the reaction mixture and stirred 1 hour at room temperature. After stirring for 1 hour, the reaction mixture was diluted with toluene (25 ml) and washed with water several times. The organic layers were dried over magnesium sulfate, filtered and the toluene rotavapped off to afford a white solid. After column chromatography, the product was obtained as a white solid in approximately 70% yield. at approximately 5° C After stirring for 1 hour washed with water several times The organic layers were dried over magnesium sulfate filtered to afford a white solid After column chromatography, the product was obtained as a white solid in approximately 70% yield

実験手順: A solution of N'-t-butyl-N'-benzoylhydrazine (0.5 g, 0.00026 mol) in 10 ml of toluene was treated with 50% sodium hydroxide (0.6 g) followed by isonicotinyl chloride hydrochloride (0.47 g, 0.0026 mol). The mixture was stirred at 23° C. overnight. The solids were removed by filtration and washed with water followed by ether to afford N'-t-butyl-N-isonicotinyl-N'-benzoylhydrazine. The solids were removed by filtration washed with water
