Procedure

2-Fluoro-4-methoxyphenylethylamine ((a): 1 equivalent), 4-nitroanthranilic acid ((b): 1 equivalent), HBTU (1.5 equivalents), and dry THF (0.5 M in (a)) were added to a dry round bottom flask. The mixture was allowed to stir for 10 hours at room temperature. The reaction was then dry loaded onto silica gel and purified via flash chromatography using hexanes/ethyl acetate. The pure fractions were combined and concentrated in vacuo to yield the product ((c): 2-amino-N-[2-(2-fluoro-4-methoxy-phenyl)-ethyl]-4-nitro-benzamide) as a pure solid.
