1-{6-[(1E)-N-(2,4,6-Trimethylphenyl)ethanimidoyl]pyridin-2-yl}ethan-1-one → 2-[1-(2,4,6-Trimethylphenylimino)ethyl]-6-[1-(4-propoxy-3,5-diphenylphenylimino)ethyl]pyridine

Participants

Reaction Steps

2-[1-(2,4,6-trimethylphenylimino)ethyl]-6-acetylpyridine (387 mg, 1.38 mmol) and 4-propoxy-3,5-diphenylaniline (440 mg, 1.45 mmol) were dissolved in 50 ml of toluene. To this solution, 4 Å molecular sieves were added. After standing for 1 day the mixture was filtered. The solvent was removed in vacuo. The residue was crystallised from cold ethanol. The product was isolated as a yellow treacle (700 mg) and used as such.
