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) drop wise at 15° C. After stirring for 2 hr at room temperature, the mixture was washed with water and then 2 N aq. hydrochloric acid. The organic layer was dried over anhy. Na2SO4, and after filtration, the solvent was removed under reduced pressure. The product N-(4-bromo-3-chloro-phenyl)-3-chloro-propionamide (8.20 g, 95% yield) was obtained as oil. MS: 298.0 (M+H)+.
