Procedure

To a solution of compound 4a (0.56 g, 2 mmole) in anhydrous acetone (10 mL) were added potassium carbonate (0.69 g, 5 mmole) and 2,4-difluorobenzyl bromide (0.56 mL, 4.4 mmol) and refluxed 8 hr. After cooled to room temperature, the reaction mixture was filtered through Celite and concentrated. The residue was extracted with ethyl acetate and dried over anhydrous magnesium sulfate, then concentrated and recrystallized with hot methanol.
