| 反応物 | 2-(Ethoxymethylene)propanedinitrile | HCID 67152 | — |
| 反応物 | N2,4-diphenylpyridine-2,3-diamine | HCID 59346194 | — |
| 溶媒 | Isopropanol | HCID 3776 | — |
| 生成物 | 3.7-diphenyl-3H-imidazo[4,5-b]pyridine | HCID 59346167 | 75% |
反応手順
0.70 mol of N2,4-diphenylpyridine-2,3-diamine and 2.56 mol of ethoxymethylene malononitrile were 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 75%.
