실험 절차

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 1 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: m.p. 167°-170° C.
