실험 절차

To a stirred solution of 2-amino-N-(5-chloropyridin-2-yl)benzamide (1.65 g, 6.66 mmol) in tetrahydrofuran (60 mL)and diisopropylethyl amine (1.28 mL) was added bromoacetyl bromide (0.64 mL, 7.32 mmol) dropwise at 0° C. The reaction mixture was warmed to room temperature and stirred overnight. Diluted the reaction mixture with ethyl acetate (120 mL) and water (50 mL). Separated the organic layer and washed with water (25 mL), saturated sodium bicarbonate (50 mL), 0.2 N hydrochloric acid (25 mL), water (50 m). Dried over sodium sulfate and remove the solvent to get crude product (2.2 g), which was used as such in the following step.
