Substituted pyridines. Dehydrogenation, desamination, and n-desmethylation of 4-amino-1, 2, 5-trimethylpiperidine and (1, 2, 5-trimethyl-4-piperidyl)benzylideneamine

4-Amino-1, 2, 5-trimethylpiperidine and (1, 2, 5-trimethyl-4-piperidyl)benzylideneamine are partially converted into α, Β′-lutidine as a result of dehydrogenation, desamination, and N-desalkylation over a type K-12 dehydrogenating catalyst. © 1970 The Faraday Press, Inc.
