실험 절차

To a solution of 2-chloro-5-fluoropyridin-4-amine (200 mg, 1.36 mmol) in dry N,N-dimethylformamide (10 mL) was added sodium hydride (65.5 mg, 2.73 mmol) in one portion at room temperature under N2. The reaction mixture was then stirred for 15 min and then a solution of 2,4,6-trichlorobenzoyl chloride (320 uL, 2.0 mmol) in N,N-dimethylforamide (400 uL) was added dropwise. The mixture was stirred at room temperature for 10 mins, and then poured into water (30 mL). The mixture was extracted with ethyl acetate (2×50 mL), and combined organic extracts were dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (0-5% methanol/dichloromethane) to give 2,4,6-trichloro-N-(2-chloro-5-fluoropyridin-4-yl)benzamide (260 mg, yield: 54%). 1H NMR (DMSO-d6, 400 MHz): δ 11.52 (s, 1H), 8.49 (s, 1H), 8.33 (d, J=5.5 Hz, 1H), 7.84 (s, 2H). LCMS (ESI) m/z: 354.9 [M+H+].
