Procedure
7-Benzyl-2,7-diazabicyclo[3.3.0]octane (Example Jc) is reacted with ethyl chloroformate analogously to Example Oa) to give ethyl 7-benzyl-2,7-diazabicyclo[3.3.0]octane-2-carboxylate, and this is then debenzylated hydrogenolytically analogously to Example Jd). A colorless oil of boiling point 90° C./0.1 mbar is obtained.
