Following the procedure outlined for the preparation of Example 1, N-[4-(5-hydroxy-pyridin-2-yloxy)-benzyl]-acetamide (0.25 g, 0.97 mmol) when treated with 5-bromo-5-(2-ethoxy-ethyl)-pyrimidine-2,4,6-trione (0.20 g, 0.80 mmol), 1,5,7-trazabicyclo[4.4.0]dec-5-ene bound to polystyrene crosslinked with 2% DVB (PTBD, Fluka, 0.77 g) and 4 mL of acetonitrile, will afford N-(4-{5-[5-(2-Ethoxy-ethyl)-2,4,6-trioxo-hexahydro-pyrimidin-5-yloxy]-pyridin-2-yloxy}-benzyl)-acetamide. Expected MS (m/z, APCI): 455 [M−H]−.
