Procedure

) 5.0 g of the known compound 4-(5-heptyl-2-pyrimidyl)phenol are dissolved in 70 ml of dimethyl sulfoxide together with 1.35 g of pentaerythrityl tetrabromide. 15 g of finely powdered potassium carbonate are added, and the mixture is stirred at 80° C. for 16 h. Conventional work-up gives 2.1 g of tetrakis[4-(5-heptyl-2-pyrimidyl)phenyloxymethyl]methane, m.p. 179°.
