| Reactant | Ethyl 1-(carbamothioylmethyl)-1H-pyrazole-4-carboxylate | HCID 58127901 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 58127481 | HCID 58127481 | 93% |
Reaction Steps
A solution (24 mL) of the compound (2.2 g, 10.2 mmol) obtained in Example 1b and 2-bromo-1-(3-nitrophenyl)ethanone (3.0 g, 12.3 mmol) in ethanol was heated under reflux overnight, and the mixture was cooled to room temperature. The solvent was evaporated under reduced pressure, and the produced crude title compound was recrystallized (ethyl acetate-hexane) to give the title compound (3.4 g, 78%) as colorless crystals.
