Procedure

Aminoguanidine bicarbonate (38 g, 0.5 mole) was slurried in 150 ml of water and phosphoric acid (59.5 g of 85% H3PO4, 0.5 mole) dropped in causing the evolution of carbon dioxide. After stirring about a half hour a clear solution resulted. Approximately one half the solvent was vacuum stripped and the remaining solution cooled to precipitate the product. The solids were filtered, ethanol washed and vacuum dried to give 76.3 g of product melting 140.5°-142.5° C.
