1-Aminopyrrole → 2-[1-(2,6-Diethylphenylimino)ethyl]-6-[1-(1-pyrrolylimino)ethyl]pyridine

Participants

Reaction Steps

Monoimine 2-[1-(2,6-diethylphenylimino)ethyl]-6-acetylpyridine (8, 1.5 g, 5.1 mmol) and 1-aminopyrrole (460 mg, 5.6 mmol) were dissolved in 25 ml of toluene. To this solution, molecular sieves (4 Å) were added. After standing for 16 hours the mixture was filtered. The solvent was removed in vacuo. The residue was crystallised from ethanol. Yield 845 mg (46%) of mixed diimine 13.
