Abstract
[6,8‐^14^C~2~]‐Bisaramil: 3‐methyl‐7‐ethyl‐9α‐(4‐chlorobenzoyloxy)‐3,7‐diazabicyclo/3.3.1./nonane‐[6,8‐^14^C~2~] monohydrochloride and [7‐N‐D~5~‐ethyl]‐Bisaramil: 3‐methyl‐7‐[D~5~‐ethyl]‐9α‐(4‐chlorobenzoyloxy)‐3,7‐diazabicyclo/3.3.1./nonane monohydrochloride were synthesized in four steps from ^14^CO~2~ (6% overall yield) and in six steps from [D~6~]‐ethanol (4% overall yield), respectively.
