To a −78° C. solution of 11.56 g of 3-(2,6-dibromo-4-methoxyphenyl)-propionic acid in 300 mL of CH2Cl2 was added dropwise 17.1 mL of a 1.0M solution of oxalyl bromide, then 1.7 mL of DMF. The mixture was allowed to warm to room temperature. When gas evolution ceased, the mixture was recooled to −78° C. Diisopropyl ethylamine (7.14 mL) was added dropwise, then a solution of 5.54 g of 2,6-dichloroaniline in 10 mL of CH2Cl2 was added dropwise. The mixture was allowed to warm to room temperature, then stirred overnight at this temperature. The white precipitate was collected to yield the N-(2,6-Dichlorophenyl)-3-(2,6-dibromo-4-methoxyphenyl)-propionamide as a white solid. The filtrate was concentrated and recrystallized from EtOH to yield an additional amount of N-(2,6-Dichlorophenyl)-3-(2,6-dibromo-4-methoxyphenyl)-propionamide as a white solid. Mass spectrum (ESI) 481.9 (M+1). 1H NMR (500 MHz, DMSO-d6): δ 9.89 (s, 1H); 7.53 (d, J=8.2 Hz, 2H); 7.34 (t, J=8.0 Hz, 1H); 7.27 (s, 2H); 3.77 (s, 3H); 3.16 (m, 2H); 2.53 (m, 2H).
