Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Reactant | N-[4-(N-acetyl-N-phenylamino)butyl]phthalimide | HCID 19956978 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 4-(N-acetyl-N-phenylamino)butylamine | HCID 19956980 | 80.7% |
Reaction Steps
A mixture of N-[4-(N-acetyl-N-phenylamino)butyl]phthalimide (9.2 g), hydrazine monohydrate (10 ml) and ethanol (200 ml) was heated under reflux for 1 hour. The deposited crystals were separated by filtration, and the filtrate was concentrated under reduced pressure to obtain 4-(N-acetyl-N-phenylamino)butylamine (4.55 g, 80.7%) as an oil.
