On heating in dry DMSO, in the presence of potassium t-butoxide, the N-nitrosamine of (4a alpha,8a beta,9a beta,10a alpha)-tetradecahydroacridine is completely converted into the N-nitrosamine of (4a alpha,8a alpha,9a alpha,10a beta)-tetradecahydroacridine. Under similar conditions, the N-nitrosamine of (4a alpha,8a alpha,9a beta,10a alpha)-tetradecahydroacridine yields a ternary equilibrium mixture containing itself (19%), and the N-nitrosamines of (4a alpha,8a beta,9a alpha,10a beta)-tetradecahydroacridine (46%) and the so far unknown (4a alpha,8a alpha,9a beta,10a beta)-tetradecahydroacridine (35%). The resulting N-nitrosamines can be smoothly denitrosated to the corresponding secondary amines.
