Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl Acetoacetate | HCID 8868 | — |
| Reactant | 4-Tert-butylphenylhydrazine hydrochloride | HCID 16217458 | — |
| Solvent | Acetic Acid | HCID 176 | — |
| Product | HCID 178429256 | HCID 178429256 | 78.5% |
Reaction Steps
4-t-Butylphenylhydrazine hydrochloride (24.2 g, 120 mmol) in acetic acid (600 mL) was stirred with ethyl acetoacetate (16.4 mL, 129 mmol) at 100° C. for 22 hours. The solvent was removed by distillation under reduced pressure, and the resulting solid was recrystallized from chloroform (70 ml, 40° C.)-diethyl ether (200 mL, 0° C.), washed with diethyl ether and dried under reduced pressure to give 21.7 g of the desired product (78% yield).
