Reaction Steps

A mixture of 15.0 g (0.037 mol) of 2,4,6-tris(2,4-dihydroxyphenyl)-1,3,5-triazine and 80 ml of diglyme (Fluka 99.5%) is admixed under nitrogen in succession with 9.2 g (0.139 mol) of pulverized KOH (Fluka, 85%), 0.3 g (0,002 mol of potassium iodide (Fluka, 99.5% ) and 29.5 g (0.163 mol) of ethyl 2-bromopropionate (Fluka, 98%). The mixture is heated with stirring at 108° C. for 19 h. The inorganic precipitate is filtered off hot; the solvent is removed on a rotary evaporator. The crude product is taken up in 100 ml of ethyl acetate (T=60° C. ) and the mixture is filtered through a silica gel bed (silica gel 60, 230-400 mesh, Ø=6 cm, h=4 cm) and with 300 ml of ethyl acetate.
