Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Nicotinoyl chloride | HCID 82604 | — |
| Reactant | 4'-Hydroxyflavone | HCID 229016 | — |
| Solvent | Pyridine | HCID 1049 | — |
| Product | HCID 11573720 | HCID 11573720 | 69.5% |
Reaction Steps
In a 50 mL round-bottomed flask fitted with condenser and magnetic stirrer were placed 2-(4-hydroxyphenyl)chromen-4-one (100 mg, 0.419 mmol), pyridine (5 mL) and nicotinoyl chloride (223 mg, 1.25 mmol). The reaction mixture was stirred for 24 h at rt under nitrogen. The solvent was removed under reduced pressure and crude product was purified by column chromatography using 50% EtOAc in hexane to give 100 mg of 4-(4-oxo-4H-chromen-2-yl)phenyl nicotinate (69%). MS (ES) m/z: 344.09 (M+1).
