반응 단계

A solution of 1-chloro-2-fluoro-3-nitrobenzene (983 mg, 5.60 mmol) in DMSO (3 mL) was purged with a stream of nitrogen prior to addition of phenylamine (1.0 mL, 11.2 mmol) and then stirred in a sealed tube at 100° C. for 3 h. After cooling to RT, the reaction mixture was partitioned between EtOAc and water. The organic layer was then washed with a saturated solution of KHSO4 (×3), then with water, followed by brine, dried (Na2SO4) and concentrated in vacuo affording (2-Chloro-6-nitrophenyl)phenylamine as a dark orange oil (1.35 g, 97%). 1H NMR (CDCl3, 400 MHz): δ 8.15 (1H, s), 8.03 (1H, dd, J=8.40, 1.49 Hz), 7.63 (1H, d, J=7.90 Hz), 7.32-7.23 (2H, m), 7.08-6.99 (2H, m), 6.86 (2H, d, J=7.90 Hz).
