A process for producing Gabapentin, (1-(aminomethyl)-1-cyclohexaneacetic acid) from Gabapentin hydrochloride salt. In the process the Gabapentin hydrochloride is converted to Gabapentin using inorganic base such as Barium hydroxide. Gabapentin hydrochloride is converted to Gabapentin sulfate which in turn is converted to free base using Barium hydroxide. The process is directed to improvement in the manufacture of Gabapentin which would be industrially feasible and effective Gabapentin obtained following the process of the invention is suitable as a drug especially in the treatment of cerebral diseases such as epilepsy. The above process involves simple steps and avoid the problems of the known art. In particular the process avoids severe conditions and/or complexities and can be readily adopted for industrial application. The process provides for good yield and does not involve lenghty extended process steps. It is cost-effective and can be carried out involving simple ingredients and steps of manufacture.
