Versuchsvorschrift

A mixture was prepared by dissolving 7.9 grams (0.063 mole) of diaminoguanidine, hydrochloride in 60 milliliters of lukewarm water and this mixture was added to a solution of 38.2 grams (0.125 mole) of 3,5-dibromo-2-ethoxybenzaldehyde dissolved in 500 milliliters of ethanol. To this mixture was added a solution of 8 milliliters of concentrated hydrochloric acid in 80 milliliters of ethanol. The mixture was heated at the reflux temperature for 10 minutes and thereafter cooled to 20° C. The solid 1,3-bis[(3,5-dibromo-2-ethoxybenzylidene)amino]guanidine, hydrochloride product was recovered by filtration under reduced pressure, washed with ethanol and dried. The product was recovered in a yield of 20 grams (45 percent of theoretical) and melted at 188°-190° C.
