Procedure

3,3'-(ethylenedioxy)dibenzaldehyde (1.08 g), aminoguanidine hydrochloride (1.105 g), and aminoguanidine dihydrochloride (0.005 g) were heated in 96% ethanol (6.25 mL) for 18 hr under nitrogen. Cooling and filtration gave 1.428 g of 3,3'-(ethylenedioxy)dibenzaldehyde bis(amidinohydrazone)dihydrochloride, mp 264°-6° C.
