A mixture of 25.0 g. of 1-benzyl-3-(2,6-dichlorobenzylideneamino)guanidine and 15 ml. of glacial acetic acid in 100 ml. of absolute ethanol is heated briefly to solution and then diluted with 800 ml. of a 1:1 mixture of diethyl ether-petroleum ether (b.p. 35°-60° C.). On standing, crystallization occurs. The desired product is recovered by filtration as colorless crystals, m.p. 114°-119° C.
