Abstract:The title compound was prepared by a Friedel-Crafts acylation-oxime synthesis-decarboxylation/dehydration sequence starting from commercially available 7-iodoindole with 2-(7-iodo-1H-indol-3-yl)-2-oxoacetic acid as isolated intermediate. The structural identity of the title compound was proven by elemental analysis and spectroscopic methods (IR, NMR, EI-MS), and purity was assessed by two independent HPLC methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
