実験手順
A mixture of 4-(4-[1,3,4]oxadiazol-2-yl-phenoxy)-phenol (0.90 g, 2.5 mmol), 5-Bromo-5-(2-ethoxy-ethyl)-pyrimidine-2,4,6-trione (1.0 g, 3.6 mmol), 1,5,7-trazabicyclo[4.4.0]dec-5-ene bound to polystyrene crosslinked with 2% DVB (PTBD, Fluka, 2.4 g, 6.1 mmol) and 11.7 mL of acetonitrile was shaken at 23° C. for 24 hours. The mixture was diluted with 30 mL of 25% acetic acid in methanol, filtered, and the solids were washed twice with methanol-acetic acid. The filtrate was concentrated in vacuo and purified by radial chromatography (2:1 to 1:1 hexane-ethyl acetate), affording 600 mg of 5-(2-Ethoxy-ethyl)-5-[4-(4-[1,3,4]oxadiazol-2-yl-phenoxy)-phenoxy]-pyrimidine-2,4,6-trione as a colorless solid.
