Procedure

Compound 25, FIG. 7E.25: 3,3'-(pentamethylenedioxy)di-p-anisaldehyde (0.748 g), aminoguanidine hydrochloride (0.553 g), and aminoguanidine dihydrochloride (0.01 g) were heated in methanol (5 mL) for 18 hr. Cooling and filtration gave 0.080 g of 3,3'-(pentamethylenedioxy)di-p-anisaldehyde bis(amidinohydrazone)dihydrochloride, mp 195°-8° C.
