7,7'-Dichloro-2,2'-dicarbethoxybis(5-indolyl)methane has been synthesized by cyclization of the 3,3'-dichloro-4,4'-diphenylmethanedihydrazone of ethyl pyruvate.Subsequent hydrolysis and decarboxylation of the corresponding diacid gave the unsubstituted 7,7'-dichlorobis(5-indolyl)methane.The syn-syn, syn-anti, and anti-anti forms of 3,3'-dichloro-4,4'-diphenylmethanedihydrazone of ethyl pyruvate have been separated and characterized.
