Reaction Steps

2-[1-(2,4,6-trimethylphenylimino)ethyl]-6-acetyl pyridine (3 g, 10.7 mmol), prepared according to the method disclosed in WO02/28805, and 4-eicosanoxy-3,5-diphenylaniline (5.8 g, 10.7 mmol) were dissolved in 200 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, D, was isolated as a yellow treacle (6.5 g, 8.1 mmol, 76%) after drying at 60° C. in vacuo.
