| 20120108848 | PROCESS FOR RESOLUTION OF 1-(3-HYDROXYPHENYL)-2-METHYLAMINO ETHANOL - Resolution of the title compound to its active isomer (R)-1-(3-hydroxyphenyl)-2-methylamino ethanol with (R)-naproxen as a resolving agent. | 05-03-2012 |
| 20120041212 | PROCESS FOR THE PREPARATION OF PREGABALIN - The present invention provides a new enantioselective method of preparing (S)-3-(aminomethyl)-5-methylhexanoic acid, commonly known as pregabalin. The invention also provides new chiral intermediates useful in the production of pregabalin. | 02-16-2012 |
| 20110306787 | PROCESS FOR THE PREPARATION OF GABAPENTIN - This invention discloses a process for converting gabapentin acid salt to free gabapentin, where the salt is dissolved in an organic solvent in which both gabapentin acid salt and free gabapentin are soluble. The solution is treated with a powdered alkaline base to liberate free gabapentin which will remain in solution. The insoluble alkali salt of the acid is removed by filtration. From the filtrate free gabapentin is obtained either by adding anti-solvent or by extraction with water. | 12-15-2011 |
| 20110275834 | POLYMORPH OF STRONTIUM RANELATE AND A PROCESS FOR ITS PREPARATION - This invention discloses Strontium Ranelate polymorph, designated as Form A, having a characteristic powdered x-ray diffraction pattern and infrared spectrum with a water content of about 1.5 to 2.5% and a process for its preparation. | 11-10-2011 |
