Hydrazine → 3-Chloro-4-hydroxybenzohydrazide
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine | HCID 9321 | — |
| Reactant | Methyl 3-chloro-4-hydroxybenzoate | HCID 77580 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 3-Chloro-4-hydroxybenzohydrazide | HCID 10954268 | 60% |
Reaction Steps
To a sample of methyl 3-chloro-4-hydroxybenzoate (2 g) dissolved in ethanol (50 mL) was added hydrazine (1.8 mL). The reaction was refluxed overnight under nitrogen. Upon cooling the reaction vessel, the desired product crystallized out of solution. The white solid was isolated by filtration. Recrystallization from hot ethanol gave the 3-chloro-4-hydroxybenzoic acid hydrazide in 60% yield.
