Reaction Steps

To 1.00 g (4.99 mmol) 4-(benzyloxy)phenol and 794 mg (4.99 mmol) 5-bromo-pyrimidine in 5 mL DMF are added 3.25 g (9.99 mmol) Cs2CO3 and the reaction mixture is stirred at 120° C. for 6 h in a microwave oven. Then the reaction mixture is diluted with water and extracted with EtOAc. The organic layer is dried with Na2SO4 and the solvent is removed in vacuo. The residue is purified by HPLC (MeOH/H2O/NH3).
