Versuchsvorschrift

3.4 g. Phenyl glycidyl ether and 9.6 g. 4-(2-aminoethylamino)-1,3,5-trimethylpyrimidine-2,6(1H,3H)-dione are stirred for about 24 hours at 70° C. The reaction mixture is dissolved in methanol and then separated by column chromatography, using a weakly acidic cation exchanger ("Amberlite" CG 50 II pract. (Serva)). The column is pre-treated with about 1.5 liters 0.1M methanolic triethylammonium acetate solution. The elution agent used is 0.1M methanolic triethylammonium acetate solution. The fractions containing the pure substance are evaporated, then rendered alkaline with 2N aqueous sodium hydroxide solution, extracted with methylene chloride and the extracts dried and evaporated. The light colored oil obtained becomes crystalline upon triturating with diethyl ether. After recrystallized from ethyl acetate, there are obtained 3.6 g. (44% of theory) of the desired product in the form of colorless crystals; m.p. 104°-106° C.
