실험 절차

4-Bromo-N-methyl-2-nitroaniline (100 mg, 0.43 mmol), 2-nitro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (115 mg, 0.43 mmol), biphenyl-2-yldicyclohexylphosphine (30 mg, 20 mol %) and K3PO4 (275 mg, 1.3 mmol) were suspended in DME-H2O (4:1, 5 mL), the mixture was purged with nitrogen then degassed by sonication. Pd(OAc)2 (5 mg, 5 mol %) was added, and the mixture heated to 130° C. for 10 min under microwave irradiation. The cooled mixture was diluted with EtOAc and H2O. The organics were separated and the aqueous layer extracted with EtOAc (3×50 mL). The combined organic extracts were washed with brine, dried (MgSO4), filtered and concentrated in vacuo to give the crude product as a dark brown solid (210 mg). The crude material was taken on without further purification.
