  • Patent number: 11498897
    Abstract: A preparing method for high-purity levetiracetam, comprising: adjusting the pH of an extracted aqueous layer obtained by dissociating (S)-?-ethyl-2-oxo-1-pyrrolidineacetic acid (R)-methylbenzylamine salt to 5-9; removing water; adding an organic solvent to form a solution and then performing an esterification reaction with ethyl chloroformate or methylchlorofonmate; and carrying out an ammonolysis reaction to obtain the levetiracetam. The method simplifies production process, increases yield, reduces or even avoids the use of triethylamine in the esterification process, and reduces the emission of a great amount of three wastes.

    Abstract: The present invention provides a method of making sulfur containing fluoroalkyl amines which overcomes the problems of previously known methods. Sulfur containing fluoroalkyl amines are useful as intermediates for compounds which are in turn useful for imparting water and oil repellency to textiles. Sulfur containing fluoroalkyl amines used in this manner may be found in Example 8 of Rondestvedt et al. (U.S. Pat. No. 3,655,732) wherein they are made by reacting an iodo-fluoroalkyl with an aminoalkyl thiol. Specifically, Rondestvedt et al. teaches reacting CF3(CF2)5(CH2)2I (an iodo-fluoroalkyl) with HS—CH2CH2—NH2 (an aminoalkyl thiol) to make CF3(CF2)5(CH2)2—S—CH2CH2—NH2 (a sulfur containing fluoroalkyl amine). Unlike previously known methods, the method of the present invention can achieve higher yields of sulfur containing fluoroalkyl amines without resorting to costly solvents.
