실험 절차
11.6 g of 1,3-diaminopropane (0.16 mol) and 2.62 g of Cu-II-acetylacetonate are placed into 100 ml of dimethylformamide, and the whole is heated in an inert atmosphere to 100° C. A solution of 10 g of 2-nitro-2'-hydroxy-5'-methyl-azobenzene in 50 ml of dimethylformamide is then added, and after 3 hours the reaction is finished. The conversion to 2-(2'-hydroxy-5'-methylphenyl)-benzotriazole gives a yield of 64%.
