2-Amino-6-chloro-3-nitro-benzonitrile (see Goldberg et al., J. Med. Chem., 2003, 1344; 800 mg, 4.05 mmol), 2-methoxyphenylboronic acid (800 mg, 5.26 mmol), and potassium phosphate (2.23 g, 10.5 mmol) were combined in DMA (10 mL) in a flask purged with nitrogen. Tris(dibenzylideneacetone)dipalladium(0) (185 mg, 0.2 mmol) and 2-dicyclohexylphosphino-2′-(N,N-dimethyl-amino)biphenyl (159 mg, 0.4 mmol) were added, and the reaction stirred at 68° C. under nitrogen for 16 h. The solution was diluted with EtOAc (50 mL), and washed with 1N HCl and brine. Organics were dried (MgSO4) and concentrated in vacuo.
