実験手順

To a solution of 4-bromo-3-chloroaniline (6.0 g, 29.1 mmol) and pyridine (3.45 g, 43.6 mmol) in 1,2-dichloroethane (50 mL) was added 3-chloropropionyl chloride (5.53 g, 43.6 mmol) dropwise at 15° C. After stirring for 2 hours at room temperature, the mixture was washed with water and then hydrochloric acid (2 N, aqueous). The organic layer was dried over anhydrous sodium sulfate. After filtration, the solvent was removed under reduced pressure. The product N-(4-bromo-3-chloro-phenyl)-3-chloro-propionamide (8.20 g, yield: 95%) was obtained as an oil. MS: 298.0 (M+H+)+.
