Summary:The present invention provides a method for chiral resolution of Trolox. The present disclosure relates to a method for producing a solid salt of a compound of formula I, wherein an amide-based solvent is added to a sample, which contains a compound of formula I, while being assumed to contain a compound of formula II, in the presence of an optical resolution agent. Formula I: (R)-6-hydroxy-2, 5, 7, 8-tetramethylchroman-2-carboxylic acid (hereinafter referred to R Trolox) Formula II: (S)-6-hydroxy-2, 5, 7, 8-tetramethylchroman-2-carboxylic acid (hereinafter referred to S Trolox) La présente invention concerne un procédé de résolution chirale de Trolox. La présente invention concerne un procédé de production d'un sel solide d'un composé de formule I, un solvant à base d'amide étant ajouté à un échantillon, qui contient un composé de formule I, tout en étant supposé contenir un composé de formule II, en présence d'un agent de résolution optique. Formule I : Acide (R)-6-hydroxy-2,5,7, 8-tétraméthylchroman-2-carboxylique (désigné ci-après par R Trolox). Formule II : Acide (S)-6-hydroxy-2,5,7, 8-tétraméthylchroman-2-carboxylique (désigné ci-après par S Trolox) トロロックスのキラル分割のための方法を提供すること。本開示は、式Iの化合物の固体塩を製造する方法であって、式Iの化合物を含み、式IIの化合物を含むと推測される試料に、光学分割剤の存在下でアミド系溶媒を添加することを含む方法: 式I:(R)-6-ヒドロキシ-2,5,7,8-テトラメチルクロマン-2-カルボン酸(以下、Rトロロックス) 式II:(S)-6-ヒドロキシ-2,5,7,8-テトラメチルクロマン-2-カルボン酸(以下、Sトロロックス)に関する。
