The present invention refers to a new addition salt of N-amino-N'-pentylguanidine, particularly to the oxalate addition salt of N-amino-N'-pentylguanidine. The process for preparing said oxalate addition salt comprises the steps of: a) reacting the N-amino-N'-pentylguanidine, as a free base or in a salt form, with oxalic acid in a polar medium; and b) recovering the product in a solid form.
This addition salt is useful for obtaining the tegaserod free base with a better purity and yield.
