Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Reactant | (2Z)-3-[(1-Methylethyl)amino]-3-(methylthio)-2-propenenitrile | HCID 86652503 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 55285667 | HCID 55285667 | 62.4% |
Reaction Steps
A mixture of (Z)-3-(isopropylamino)-3-(methylthio)acrylonitrile (0.413 g, 2.64 mmol) and hydrazine monohydrate (0.38 mL, 7.93 mmol) in EtOH (6 mL) was heated to reflux for 16 hours. After cooling to room temperature, the reaction mixture was concentrated. The residue was purified by column chromatography, eluting with ethyl acetate, DCM/MeOH (9:1) to give N3-isopropyl-1H-pyrazole-3,5-diamine (0.231 g, 62% over 2 steps) as an oil.
