Reaction Steps

A solution of 2-(α-bromophenylacetylamino)isobutyric acid (1.9 g) in dichloromethane (30 mL) was cooled to 0° C., to which dimethylaminopropylethylcarbodiimide hydrochloride (1.3 g) was added. The mixture was stirred for 10 minutes at 0° C. to room temperature. 2,5-Dichloroaniline (1.0 g) was added to the mixture, which was stirred overnight at room temperature. The reaction solution was poured into water and the mixture was extracted with chloroform. The organic layer was washed with water and dried over anhydrous sodium sulfate. After distilling off the solvent, 2.3 g of N-(2,5-dichlorophenyl)-2-(α-bromophenylacetylamino)isobutyramide was obtained as viscous liquid.
