Procedure

2-Methyl-3-(2-amidinohydrazono)butyl-1,4-naphthoquinone hydrochloride, mp 108°-110° C. is prepared in a manner similar to that of Example 1 by reaction of aminoguanidine hydrochloride with 2-methyl-3-(3-oxobutyl)-1,4-naphthoquinone. This naphthoquinone is prepared by reaction of 2-methyl-1,4-naphthoquinone, 4-oxopentanoic acid, silver nitrate and ammonium peroxydisulfide in a manner similar to that described above.
