TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The step (a) is carried out at ambient temperature to reflux temperature, preferably at reflux temperature. The crude compound of (IV) in the step (a) is purified by distillation by different techniques. The step (b) is carried out at a temperature of 45-120 degrees C, such as 45-110 degrees C, preferably at reflux temperature of the solvent used. (VI) in the step (c) is prepared by dispersing finely powdered (V) that is sieved through 50-300 mesh and suspended in water or optionally micronized in water for required period of time, and contacting the suspension with the genetically modified nitrilase enzyme 2-30 U/g of substrate at appropriate pH, preferably 7.5 plus minus 0.2 under stirring at 25-50 degrees C. The loading of (V) in the step (c) is in 50-100 g/l of water, preferably 65-85 g/l of water. The loading of the genetically modified nitrilase enzyme for the preparation of (VI) in the step (c) uses 4-25 U/g of (V), preferably 6-20 U/g. The pH is maintained by a buffer such as phosphate or acetate buffer or with the addition of acid or base. The step (c) is carried out at a temperature of 25-40 degrees C, preferably 30-37 degrees C. The reaction mixture after the preparation of (VI) in the step (c) is used directly for the subsequent step after removal of protein matter and optionally the solution is concentrated by the removal of 50-75% of water or optionally (VI) is isolated by acidification. The preparation of (VI) in the step (c) comprises isolation (VI) after acidification followed by extraction of (VI) into an organic solvent-I and subsequently extracting as salt in water using a base-I. The reduction of (VI) to (VII) by the catalytic hydrogenation in the step (d) is carried out at a pH of greater than 10, while in case of the reduction of salts of (VI) to gabapentin is carried out at pH less than 10. The ammonium salt of (VI) from enzymatic reaction mass is converted in situ into other alkali and alkaline earth salts as such with the total volume or after partial concentration, where the concentration is 25-50%. The step (a1) is carried out at a temperature of 30-150 degrees C, preferably 80-90 degrees C. The organic base salt is obtained from converting isolated (VI) into its salt with appropriate base or extracting (VI) with the solvent-I followed by extraction with ammonia or an organic amine in water or water containing water miscible solvent, isolating ammonium or organic amine salt of (VI), treatment of the enzymatic reaction mass containing ammonium salt of (VI) with an organic amine, carrying out enzymatic reaction of partially concentrated ammonium salt of (VI) or its salt after charcoal treatment. The preparation of alkali or alkaline earth metal salts comprises converting isolated (VI) into its salt or extracting the (VI) with an organic solvent-II followed by extraction with alkali metal or alkaline metal hydroxide or carbonates in water or water contain water miscible solvent, or in situ conversion of the ammonium salt of (VI) in enzymatic reaction mass or partially concentrated, into other alkali and alkaline earth metal salts. The step (a1) is carried out after removing the catalyst followed by solvent-I wash to the reaction mass or solvent-I wash after evaporation to reduce the gabalactam content at 30-150 degrees C, preferably 50-60 degrees C.

EXAMPLE - 641.84 g of Ammonium salt of 1-cyano cyclohexane-1-acetic acid in water was charged to precleaned autoclave. Then 7.5 g of Raney nickel was charged to the autoclave and the suspension was hydrogenated for 4 hours at 60 degrees C and 1 hour at 50 degrees C with a hydrogen pressure of 15 kg/cm . The reaction mass was filtered after the completion of reaction to remove Raney nickel. The clear filtrate was washed with dicholoromethane. The aqueous layer was evaported under vacuum at less than 45 degrees C to give wet gabapentin of 62 g having a moisture content of 28.59%.
