Procedure

15.60 g (0.0235 mol) of 2,4,6-tris(2-hydroxy-4-(1-methoxycarbonylethoxy)phenyl)-1,3,5-triazine are refluxed for 10 h with 0.45 g (0.00235 mol) of p-toluenesulfonic acid monohydrate and 14.85 ml (0.094 mol) of octanol (isomer mixture) in 50 ml of xylene until methanol is no longer split off. The reaction mixture is then cooled, washed with water and dried using MgSO4. The solvent is concentrated and the residue is chromatographed over silica gel, giving a yellowish resinous substance of the following structure:
