Abstract

The invention relates to a novel method for producing robenidine or derivatives thereof of general formula (I) wherein X means a halogen atom, using hydrazine hydrate and a cyanogen compound as the starting materials. The two educts are first converted into a diaminoguanidine of general formula (III) in a C1-4 alcohol or a C1-4 alcohol-water mixture as the solvent or in an aprotic polar organic solvent, Y being a halogen atom or tosyl. Said diaminoguanidine is then directly reacted with a p-halobenzaldehyde of general formula (IV) without isolation in a C1-4 alcohol, a C1-4 alcohol-water mixture or in an aprotic polar organic solvent-water mixture as the solvent to form the end product.
