Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Diethyl bromomalonate | HCID 69637 | — |
| Reactant | Ethyl 2-aminopyridine-3-carboxylate | HCID 12433260 | — |
| Solvent | Acetone | HCID 180 | — |
| Product | HCID 135817522 | HCID 135817522 | 34.8% |
Reaction Steps
A mixture of diethyl bromomalonate (26 ml) and ethyl 2-aminonicotinate (13.3 g) was allowed to react at 80°-90° C. for 6 hours under nitrogen atmosphere. After completion of the reaction, the mixture was cooled to room temperature, and acetone (100 ml) was added thereto. The precipitated crystals were collected by filtration, affording 3,8-diethoxycarbonyl-2-hydroxy-imidazo[1,2-a]pyridine hydrobromide (9.98 g, yield 34.8%).
