Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Histamine | HCID 774 | — |
| Reactant | 2-Chloro-3-nitropyridine | HCID 79613 | — |
| Solvent | Isopropanol | HCID 3776 | — |
| Product | HCID 178526675 | HCID 178526675 | 65% |
Reaction Steps
1.14 g (10.2 mmol) of histamine base and 1.62 g (10.2 mmol) of 2-chloro-3-nitropyridine are brought to reflux in 5 ml of 2-propanol for 3 h. Evaporation of the solvent under reduced pressure and purification of the solid residue by chromatography on a column of silica gel, eluted with chloroform containing increasing amounts of methanol (5, 10 and 20%), provide the title compound. M.p.: 178°-180° C. (yield 65%; ethanol:water).
