Procedure

3,3'-(trimethylenedioxy)di-p-anisaldehyde (1.032 g), aminoguanidine hydrochloride (0.829 g), and aminoguanidine dihydrochloride (0.02 g) were heated in 95% methanol (10.5 mL) for 16 hr. Cooling and filtration gave 1.372 g of 3,3'-(trimethylenedioxy)di-p-anisaldehyde bis(amidinohydrazone)dihydrochloride, mp 233°-5° C.
