It has been found that potassamide reacts with 5-bromo-6-amino-3-(4-methylamino-butyl)pyridine to give a mixture of the starting material, 6-aminonicotine, and 1-methyl-8-amino-2,3,4,5-tetrahydro[4,3-b]azepine. The latter has been obtained independently from 1-methyl-9-cyano-2,3,4,5,7,8-hexahydropyrido[4,3-b]azepin-8-one.
