Ethyl 2-benzoyl-3-ethoxyacrylate → HCID 178471953, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl 2-benzoyl-3-ethoxyacrylate | HCID 98006 | — |
| Reactant | 1-(furan-2-ylmethyl)-1H-pyrazol-5-amine | HCID 2546182 | — |
| Product | HCID 178471953 | HCID 178471953 | — |
Reaction Steps
163 g. of 1-(2-furyl)methyl-5-aminopyrazole (1 mol.) and 248 g. of ethoxymethylene benzoyl acetic acid ethyl ester (1 mol.) are heated at 130° until no more alcohol distils off (approximately 1 hour). The oily residue crystallizes and yields on cooling and recrystallization from hexane 310 g. of [[[1-(2-furyl)methyl-5-pyrazolyl]-amino]methylene]benzoyl acetic acid ethyl ester (85%), m.p. 75°-77°.
