Versuchsvorschrift

N'-t-butyl-N-benzoylhydrazine (1.0 g, 0.0052 mol) was suspended in 20 ml of toluene. Isonicotinoyl chloride hydrochloride (0.93 g, 0.0052 mol) was added and then a solution of sodium hydroxide (1.25 g of 50% aqueous NaOH) in 5 ml of water was added dropwise. After stirring at 23° C. for 2 hours, the solids were removed by filtration, washed with water and dried in air. The crude product was chromatographed on silica gel using 5% methanol/methylene chloride as eluant to afford pure N'-t-butyl-N-benzoyl-N'-isonicotinoylhydrazine: m.p. >210° C.
