반응 단계

To a solution of 3-nitrobenzoic acid (3.0 g ) and 2,3-dimethylaniline (2.17 g) in 20 mL of DMF was added 1-hydroxybenzotriazole (2.75 g), EDC (3.44 g) and triethylamine (7.39 mL). The resulting solution was stirred for 16 h. The DMF was evaporated in vacuo and the residue was partitioned with ethyl acetate and water. The ethyl acetate layer was extracted w/50 mL each of 2% potassium hydrogen sulfate, saturated sodium bicarbonate, saturated sodium chloride, dried over magnesium sulfate and concentrated in vacuo to afford the title compound as a solid.
