Reaction Steps

21 ml of a 2.0 M solution of trimethylaluminium in hexane are added under argon to 5.5 g (0.042 mol) of dibutylamine in 35 ml of anhydrous dichloromethane. After 15 minutes, 10.5 g (0.014 mol) of 2,4,6-tris(4-[1-ethoxycarbonyl-1-methylethoxy]-2-hydroxyphenyl)-1,3,5-triazine (Compound 1) are added to the reaction mixture. After 1 day 10 ml of anhydrous xylene are added and the dichloromethane is distilled off. The reaction mixture is subsequently heated at 130° C. for 2 days and then 10 ml of 20% HCl are added. The reaction mixture is extracted with ethyl acetate and the organic phase is dried over magnesium sulfate. The title product is obtained after column chromatography (Compound 15: 1H NMR(CDCl3): 0.80 (t, J=7.1 Hz,9H), 0.90 (t, J=7.1 Hz,9H), 1.12-1.4 (m, 24H), 1.71 (s, 27H), 3.29-3.35 (m, 6H), 3.50-3.55 (m, 6H), 6.39-6.60 (m, 6H), 8.00-8.02 (m, 3H), 13.24 (s, 3H)) and also
