More Information
Summary:This invention relates to a method for photoracemizing enantiomers of a substituted 2-trifluoromethyl-2H-chromene-3-carboxylic acid or ester, a substituted 2-trifluoromethyl-1,2-dihydro-quinoline-3-carboxylic acid or ester, a substituted 2-trifluoromethyl-2H-thiochromene-3-carboxylic acid or ester, or a pharmaceutically acceptable salt of the acids or esters, using a high intensity UV light source. L'invention concerne un procédé de photoracémisation d'énantiomères d'un acide ou d'un ester 2-trifluorométhyle-2H, chromène-3-carboxylique substitué, d'un acide ou d'un ester 2-trifluorométhyle-1,2-dihydro-quinoline-3-carboxylique substitué, d'un acide ou d'un ester 2-trifluorométhyle-2H-thiochromène-3-carboxylique, ou d'un sel pharmaceutiquement acceptable desdits acides ou desdits esters, à l'aide d'une source lumineuse U.V. à haute intensité.
