Abstract—New approaches have been developed here: 4-methyl-benzoic acid first reacted with thionyl chloride, then with caprolactam, and last with N-bromosuccinimide to produce the 4-bromomethyl benzoyl caprolactam. Further, N, N, N-triethyl-4-[(hexahydro-2-oxo-1H-azepin-1-yl) carbonyl]-, Bromine was prepared through the reaction with triethylamine and 4-bromomethyl benzoyl caprolactam. The total yield was 61%. 4-methyl-benzoic acid reacted N-bromosuccinimide, then with chlorohydric acid, and last with caprolactam to produce 4 - chloromethyl benzoyl caprolactam. N, N, N-triethyl-4-[( hexahydro -2-oxo-1H-azepin-1-yl) carbonyl]-,Chloride was further synthesized via the reaction with triethylamine and 4 - chloromethyl benzoyl. The total yield was 41%.
Index Terms—Hydrogen peroxide bleaching, amide, activator, synthesis.
