实验步骤: 25 g of K2CO3 are added to a solution of 20 g of phenylhydrazine hydrochloride in 150 ml of methyl formate and 60 ml of water, and the mixture is refluxed for 1 hour and left at AT for 12 hours with stirring. The precipitate formed is filter-dried, and washed with a propan-2-ol/petroleum ether mixture. 18.8 g of the expected compound are obtained. the mixture is refluxed for 1 hour The precipitate formed is filter-dried washed with a propan-2-ol/petroleum ether mixture

实验步骤: A solution of N'-phenylformohydrazide (20.59 g) in dry tetrahydrofuran (750 ml) was added dropwise under nitrogen to a stirred suspension of lithium aluminium hydride (10 g) in dry tetrahydrofuran (200 ml), then the mixture was stirred and heated under reflux for 4 hours. The mixture was quenched by the slow dropwise addition of water (10 ml), followed by 5M aqueous sodium hydroxide solution (10 ml), then water (20 ml), then it was filtered, dried (MgSO4) and the solvent removed in vacuo to yield an oil. The oil was dissolved in ether, redried (MgSO4) and the solvent removed in vacuo to yield 1-methyl-2-phenylhydrazine (14.1 g) as a yellow oil. heated under reflux for 4 hours The mixture was quenched by the slow dropwise addition of water (10 ml) water (20 ml), then it was filtered dried (MgSO4) the solvent removed in vacuo to yield an oil redried (MgSO4) the solvent removed in vacuo

实验步骤: Phenylhydrazine (75 g) was added dropwise at <20° C. to stirred acetic acid (198 ml). When the addition was complete, formamide (27.9 ml) was added in one portion, and the mixture was stirred at ambient temperature for 4 hours. Water (225 ml) was added, and the resulting solid was collected by filtration, washed well with water, and dried in vacuo to give N'-phenylformohydrazide (68.8 g) as a cream solid, m.p. 138-143° C. When the addition the resulting solid was collected by filtration washed well with water dried in vacuo
