Reaction Conditions

Reaction Steps

A mixture of 20.0 g (0.048 mol) of 2-mesityl-4,6-bis(2,4-dihydroxyphenyl)-1,3,5-triazine (compound 1b), 13.8 g (0.105 mol) of n-butyl glycidyl ether (purity 95%) and 1.8 g (4.8 mmol) of ethyltriphenylphosphonium bromide (purity 97%) in 100 ml of mesitylene (purity 99%) is stirred at 140° C. under nitrogen for 21 hours. Decantation and evaporation of the remaining solvent gives 41.2 g of crude product. This is dissolved in 100 ml of ethyl acetate and filtered through a 10.5 cm layer of silica gel 60 (230-400 mesh) of diameter 7.5 cm, with elution with 3 l of ethyl acetate/hexane (1:1 mixture). The 34.0 g of solid obtained after removal of the solvent are re-dissolved in 25 ml of ethyl acetate. 250 ml of hexane are added to the viscous solution. The mixture is stirred at 0° C. for 2 hours and filtered, and the solid is dried for 24 hours at 80° C. and a pressure of 60 mmHg (8000 Pa), giving 23.0 g of the title product (compound 2) of the formula ##STR105## of m.p. 125°-131° C.
