Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Bromo-4'-nitroacetophenone | HCID 66840 | — |
| Reactant | Ethyl 1-(carbamothioylmethyl)-1H-pyrazole-4-carboxylate | HCID 58127901 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 58127583 | HCID 58127583 | 89.1% |
Reaction Steps
A solution (8 mL) of the compound (1.0 g, 4.7 mmol) obtained in Example 1b and 2-bromo-1-(4-nitrophenyl)ethanone (1.4 g, 5.6 mmol) in ethanol was heated under reflux overnight, and cooled to room temperature. The solvent was evaporated under reduced pressure, and the resulting crude title compound was recrystallized (ethyl acetate-hexane) to give the title compound (1.5 g, 89%) as colorless crystals.
