Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Bromo-1-(3-nitrophenyl)ethan-1-one | HCID 75213 | — |
| Reactant | Thionicotinamide | HCID 737155 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 4-(3-Nitrophenyl)-2-(3-pyridyl)-thiazole hydrobromide | HCID 2823874 | 92% |
Reaction Steps
A mixture of 2-bromo-3′-nitroacetophenone (5 g, 20 mmol) and thionicotinamide (2.76 g, 20 mmol) in ethanol (25 ml) was heated to reflux for 1 h, during which time extensive precipitation occurred. Filtration and drying afforded the product as a yellow solid (6.7 g, 92%).
