Participants

Reaction Steps

10 g (0.025 mol) of 2-(2,4-dihydroxyphenyl)-4,6-bis(3-methoxyphenyl)-1,3,5-triazine (prepared by the method of Example 8 starting from 3-bromoanisole), 3.8 g of potassium carbonate and 30 mg of potassium iodide are heated in 25 ml of 2-ethoxyethanol at 110 C. for one hour, followed by dropwise addition of 6.7 g (0.041 mol) of 1-bromohexane and stirring at 110 C. for a further 32 hours. After cooling, the mixture is filtered, the solid material is washed neutral with water and then washed with methanol and dried. The crude product is purified by column chromatography (250 g SiO2 35-70 μm; eluent toluene/petroleum ether 1:1). This gives the compound of formula ##STR24##
