Versuchsvorschrift

An amount of 200 mg (1.01 mmol) of 2-carboxymethyl-4-fluoro-benzoic acid and urea (72.47 mg, 1.22 mmol) were heated neat at 180-190° C. for 45 min. The mixture is cooled to room temperature followed by recrystallization from water and anhydrous ether to give 175 mg (80% yield) of brown solid. MS (ESI) m/z 179.15 (M+1).
