Participants

Reaction Steps

2,4-Bis{2-hydroxy-N-(2,2,6,6-tetramethyl-4-piperidyl)ethylamino}-6-chloro-1,3,5-triazine (8.0 g) and triethylenetetramine (0.5 g) were dissolved in dioxane (100 ml) and to the solution was added an aqueous solution of sodium hydroxide (0.7 g) in water (10 ml). The mixture was heated to reflux for 6 hours. Dioxane was distilled off from the reaction mixture and the residue was extracted with benzene. The extract was treated with silica gel column chromatography (eluent=ethyl acetate:benzene:ethanol:triethylamine=20:4:2:1) to give the desired product as white crystals melting at 158° C.
