Abstract: | N-Methylanabasine undergoes dimerization in the presence of Raney nickel at 170–180°C to give 5,5 -bis(1-methyl-2-piperidyl)-2,2 -dipyridyl. Oxidation of the latter gives 6,6 -bis(nicotinic acid).Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1224–1225, September, 1978. |
