反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mechanically stirred solution of N'-t-butyl-N-t-butoxycarbonylhydrazine (61 g, 0.32 mol) in toluene (120 ml) cooled in an ice bath, was treated dropwise and simultaneously with 50% sodium hydroxide (31 g) in water (50 ml) and benzoyl chloride (45 g). The addition was complete in 20 minutes and the resulting mixture was warmed to room temperature and allowed to stir for one hour. The resulting white solid was filtered, washed with water and air dried to afford 94 g of N-t-butoxycarbonyl-N'-benzoyl-N'-t-butylhydrazine, mp. 167-170° C. The addition The resulting white solid was filtered washed with water and air dried
