A solution of 1,2-difluoro-4-nitro-benzene (0.96 g, 6.0 mmole) and benzyl methylamine (0.79 g, 6.6 mmole) in 4 mL of anhydrous DMF is heated with K2CO3 (0.41 g, 3.0 mmole) at 80° C. for 16 hours. After removal of the solvent, the residue is purified on flash chromatography with EtOAc/Hexanes (0-15%), yielding yellow oil 1.05 g (4.0 mmole) 67% of benzyl-(2-fluoro-4-nitro-phenyl)-methylamine.
