Under nitrogen, 32.4 g (128 mmol) of 11-bromo-1-undecanol are added at 80° C. to a solution of 20.0 g (54 mmol) of 2-phenyl-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine, 6.6 g (109 mmol) of potassium hydroxide and 150 ml of diglyme. The mixture is heated at 100° C. for 14 hours and filtered while hot, and the filtrate is cooled to 0° C. The solid which crystallizes therefrom is filtered off, pressed and dried for 24 hours under reduced pressure (60 mmHg, 60° C.), giving 27.6 g (72% yield) of 2-phenyl-4,6-bis[2-hydroxy-4-(11-hydroxyundecyloxy)phenyl]-1,3,5-triazine as a pale yellow solid of melting point 126°-135° C.
