실험 절차

2-Fluoroaniline (1.45 mL, 15 mmol) was dissolved in DMF (10 mL) and sodium hydride (0.58 g, 15 mmol) was added and the mixture was stirred for 30 minutes. 2-Fluoronitrobenzene (1.05 mL, 10 mmol) was added and the mixture was stirred for 16 hours. The mixture was quenched with saturated NH4Cl and diluted with ether. The mixture was washed with water, brine, dried over anhydrous magnesium sulfate, and concentrated. The crude product was purified via Isco chromatography (Redisep, silica, gradient 5-30% ethyl acetate in hexane) to afford 1.4 g 2-fluoro-N-(2-nitrophenyl)aniline that was carried on directly to the next step. MS (ES) m/z 232.9.
