    摘要: This invention relates to an improved process for the preparation of amino methyl cyclo alkane acetic acids. This invention particularly relates to an improved process for the preparation of gabapentin (which is chemically known as 1-aminomethyl-1-cyclohexaneacetic acid), which is a very well known agent useful for the treatment of epilepsy and other cerebral disorders. In the chemical series of 1-amino methyl cyclo alkane-1-acetic acids, Gabapentin, which is 1-amino methyl cyclo hexane-1-acetic acid has been developed as a drug having anti convulsive properties.

    摘要: This invention relates to an improved process for the preparation of substantially pure, stable anhydrous gabapentin. Thus, cyclohexane 1,1-diacetic acid monoamide is first treated with NaOH/NaClO to form 3,3-pentamethylenebutyrolactam, which is treated with aqueous HCl solution under reflux to provide gabapentin HCl salt, which is then neutralized with NaOH followed by a dehydration step to provide substantially pure, storage-stable, pharmaceutical grade gabapentin.
