A new compound, 4‐benzylaminobenzimidazole was synthesized. The only difference between benzylaminobenzimidazole and benzylaminopurine is the presence in the former of carbon atoms instead of the nitrogen at positions 1 and 3 of the purine ring. Although the new compound has no purine ring in the molecule, it has several cytokinin activities such as stimulation of leaf growth in Raphanus and retention of chlorophyll in Brassica leaves. Benzylaminobenzimidazole has no effect on germination of tobacco seeds kept in the dark.
