We have already reported [i] the synthesis and curarelike properties of bisgramine based on bis (5-indolyl) methane with dimethylaminomethyl groups at the 3-position of the indole ring. To obtain isogramine V based on bis (5-indolyl) methane with dimethylaminoethyl groups at the 2-position, we carried out an aminolysis of a diacid chloride of 2, 2'-dihydrocarbonyl-bis (5-indolyl) methane [7] by an aqueous solution of dimethylamine, followed by lithium ...
