A variety of 3-substituted 9-methyl-3,9-diazabicyclo[3.3.1]nonanes was synthesized. 2,6-Lutidine was used as the starting material in the preparation of the requisite intermediates. In a similar sequence, chelidamic acid was transformed into 3-benzyl-7-methoxy-9-methyl-3,9-diazabicyclo [3.3.1] nonane.
