Reaction Steps
To a solution of 2-[4-(2-hydroxy-ethoxy)-3,5-dimethyl-phenyl]-5,7-diisopropoxy-3H-quinazolin-4-one (0.73 g, 1.70 mmol) in DMF (10 mL) were added PPh3 (0.49 g, 1.87 mmol) and CBr4 (0.62 g, 1.87 mmol). The reaction mixture was stirred at room temperature for 16 hours. Then, solvent was removed under reduced pressure. The residue was triturated with ether and ethyl acetate. The solid was dried and purified by the Simpliflash system (2% methanol in CH2Cl2 as eluent) to give 2-[4-(2-bromo-ethoxy)-3,5-dimethyl-phenyl]-5,7-diisopropoxy-3H-quinazolin-4-one as a white solid. Yield: 0.39 g (47%).
