Much work has been recorded in the literature concerning chlorination of photographic couplers. However, no detailed report can be found with the coupler of the structure 1. In this paper, the chlorination of 1 using SO2Cl2 in CHCl3 was shown to give the chlorination product 2. UV, IR, 1H NMR and MS of the chlorination product are compared with that of 1, and with those reported in the literature for benzoylacetanilide. Thermolysis of 2 gives a liquid fraction, HPLC shows one peak, which was identifield by 1H NMR and MS to be o-CH3COC6H4OCH2CHClC14H29. Elemental analyses as well as MS of its 2, 4-dinitrophenylhydrazone agree well with the structure assigned.
