Procedure

To a solution of Compound 5 (80 mg, 0.225 mmol) in DCM (3 mL) were added DCC (70 mg, 0.338 mmol), DMAP (5.5 mg, 0.045 mmol), and 4-fluorophenol (61.5 mg, 0.450 mmol) at room temperature. The reaction mixture was stirred overnight (about 18 hours) and filtered through Celite. The filtrate was washed with brine, and dried with Na2SO4. The solution was filtered and concentrated. The residue was subjected to chromatography over silica gel (Hexanes/EtOAc=8/1) to give (E)-4-fluorophenyl 3-(dimethylamino)-5-(4-(methoxymethoxy)-3,5-dimethyl-styryl)benzoate.
