Procedure

4,4′-(ethylenedioxy)di-m-anisaldehyde (0.99 g), aminoguanidine hydrochloride (0.829 g), and aminoguanidine dihydrochloride (0.01 g) were heated in 95% methanol (10.5 mL) under nitrogen for 16 hr. Cooling and filtration gave 1.52 g of 4,4′-(ethylenedioxy)di-m-anisaldehyde bis(amidinohydrazone) dihydrochloride, mp 322-3° C. dec.
