FUMARIC ACID SALTS OF 9,9-ALKYLEN-3,7-DIAZABICYCLO3,3,1NONANE COMPOUNDS, METHOD FOR PRODUCING THEM AND A MEDICAMENT CONTAINING SAME

摘要

1,5-Fumaric acid salts of N,N'-di-lower alkyl-substituted 9,9-alkylene-3,7-diazabicyclo[3.3.1]nonanes are described. The salts are obtained in stoichiometrically pure form and are virtually non-hygroscopic.
