실험 절차
Under nitrogen, to 2-chloro-6-nitrobenzoic acid (1.27 g, 6.28 mmol, 1.00 equiv) in CH2Cl2 (20 mL) at 23° C. was added oxalyl chloride (0.585 mL, 6.91 mmol, 1.10 equiv) and DMF (16 μL, 0.19 mmol, 3.0 mol %). After stirring for 1 hr at 23° C., the reaction mixture was cooled to 0° C. and triethylamine (2.63 mL, 18.8 mmol, 3.00 equiv) and 3-(2,2,2-trifluoroethoxy)aniline (1.20 g, 6.28 mmol, 1.00 equiv) were added. After stirring for 15 min at 0° C., 3N HCl aq (50 mL) was added. The phases were separated and the aqueous phase was extracted with CH2Cl2 (3×3.0 mL). The combined organic phases were washed with brine (3.0 mL) and dried (MgSO4). The filtrate was concentrated in vacuo and the residue was purified by column chromatography on silica gel eluting with hexanes/EtOAc to afford 965 mg of the title compound (41% yield).
