Reaction Steps

To a stirred solution of commercially available 2-Fluoro-benzoic acid ethyl ester (1 g, 6.01 mmol) and 4-Fluoro-benzylamine (0.828 g, 6.62 mmol) in dry N,N′-dimethylformamide (10 mL) in a screw cap vial was added diisopropylethylamine (0.854 g, 6.62 mmole, 1.1 mL). The resulting solution was heated to 120° C. for 4 hours. Reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate (25 mL×3). Combined organic phase was washed consecutively with water, brine before drying over sodium sulfate. Organic phase was evaporated and the residue was purified by flash chromatography to afford 2-(4-Fluoro-benzylamino)-benzoic acid ethyl ester as a clear liquid (1.23 g, 75%, LCMS calc M+H 274, obs M+H 274).
