A process for synthesis of 1-(aminomethyl)cyclohexane acetic acid hydrochloride (Gabapentin hydrochloride) comprising: a) Reaction of a mixtur e of acetic anhydride/ammonium acetate with 1,1-cyclohexane~diacetic acid to yield 3,3-pentamethylene glutarimide; b) Treatment of 3,3-pentamethylene glutarimide with sodium hydroxide in an aqueous solution up to dissolution, dripping the solution thus obtained into a to sodium hydroxide/sodium hypochlorite mixture, which is also aqueous, followed by acidification with hydrochloric acid to yield gabapentine hydrochloride.
