반응 단계

A mixture of 1-bromo-3-methyl-2-nitrobenzene (1 g, 4.63 mmol), phenylamine (422 μL, 4.63 mmol), Cs2CO3 (2.11 g, 6.48 mmol) and (R)-BINAP (5 mol %, 143 mg, 0.23 mmol) in toluene (20 mL) was degassed with a stream of nitrogen prior to addition of Pd(OAc)2 (25 mg, 0.11 mmol) and was stirred at 110° C. under a nitrogen atmosphere for 18 h. After cooling to RT, the mixture was partitioned between EtOAc and water. The organic layer was washed with brine, then dried (Na2SO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, gradient 0-35% DCM in cyclohexane) affording (3-Methyl-2-nitrophenyl)phenylamine as a red oil (931 mg, 88%). LCMS: RT 3.97 min [M+H]+ 229.1.
