Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Isopropanol | HCID 3776 | — |
| Reactant | N2,4-diphenylpyridine-2,3-diamine | HCID 59346194 | — |
| Product | 2-methyl-3,7-diphenyl-3H-imidazo[4,5-b]pyridine | HCID 68561097 | 74% |
Reaction Steps
0.70 mol of N2,4-diphenylpyridine-2,3-diamine and 2.56 mol of ethoxy ethylene malononitrile was added in 10 ml of isopropanol, and refluxed for 6 hours. The solution was removed and was purified by using column chromatography to thereby produce a solid crystalline product at a yield of 74%.
