Pharmacological Effects of Robenidine Hydrochloride Powder.

Prepared by condensation of p-chlorobenzaldehyde with N,N'-diaminoguanidine hydrochloride.Preparation of N,N'-diaminoguanidine monohydrochloride (1,3-Diaminoguanidinemonohydrochloride,CH7N5-HCl,[36062-19-8]): Starting from sodium thiocyanate, aminothiourea was prepared by addition to hydrazine hydrate and rearrangement. Then N,N'-diaminoguanidine hydrochloride was prepared by methylation and hydrazolysis with dimethyl sulfate. Finally, N,N'-diaminoguanidine hydrochloride is substituted with calcium amide.

Production method of Robenidine Hydrochloride Powder.

• Aminothiourea is produced by addition and rearrangement of sodium thiocyanate with water and hydrazine. Then N.N'-diaminoguanidine sulfate is obtained by methylation with dimethyl sulfate and hydrazinolysis. Then replace with calcium chloride to N.N'-diaminoguanidine hydrochloride.
• Finally, it is condensed with p-chlorobenzaldehyde in ethanol to produce chloroguanidine hydrochloride with 94% yield.
• The production method is based on sulfaguanidine as raw material, which is obtained by cyclization with acetylacetone. Sulfaguanidine, acetylacetone, sodium bisulfite, sodium hydroxide and water were put into the reaction kettle, heated and refluxed for about 6h.
• When the reaction liquid appears crystallization, add acetyl acetone to continue refluxing for 20 h. After recovering acetyl acetone, add appropriate amount of boiling water, filter while hot, filter cake with hot water washing, recrystallization, drying sulfadiazine.
