Synthesis
Ambenonium, [oxalyl-bis-(iminoethylen)]-bis-[ortho-(chlorobenzyl)
diethylammonium] chloride (13.2.15), is made by reacting diethyloxalate with two moles of
N,N-diethylethylendiamine, forming oxalyl-bis-(iminoethylen)-bis-N,N-diethylamine
(13.2.14), which is alkylated by two moles of 2-chlorobenzylchloride, giving ambenonium
(13.2.15) [46¨C48].
