Procedure
Combine 3-bromo-4-fluorobenzoic acid (5.0 g, 22.8 mmol) with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (4.4 g, 22.8 mmol) and N-hydroxy-succinimide (2.6 g, 22.8 mmol) in dichloromethane (75 mL) and stir at room temperature for 30 min. Add N,N-dipropylamine (4.7 mL, 34.3 mmol) and triethylamine (8.0 mL, 57.1 mol) and stir at room temperature overnight. Dilute with ethyl acetate and wash with 1 N HCl, saturated aqueous potassium carbonate, saturated aqueous sodium chloride, dry (magnesium sulfate), concentrate and purify (silica gel chromatography, eluting with 30:70 ethyl acetate:hexanes) to give the title compound.
