Abstract

The invention relates to the technical field of medicine impurity synthesis. The invention discloses a diphenylphosphinic acid derivative impurity in a sugammadex sodium intermediate gamma-ICD and a preparation method of the diphenylphosphinic acid derivative impurity. The preparation method of the impurity comprises the following steps: (1) dissolving diphenylphosphinic acid in an organic solvent, adding a certain amount of alkali under the protection of inert gas, carrying out stirring and reacting for a period of time at a certain temperature, then adding 6-total deoxy-6-total iodo-gamma-cyclodextrin, reacting for a period of time at a certain temperature, and carrying out aftertreatment to obtain a compound crude product shown as a formula I; and (2) separating and purifying the crudeproduct to obtain the single compound shown in the formula I. The invention provides a standard reference substance for quality control of the sugammadex sodium intermediate gamma-ICD, and is particularly important for impurity research and quality control of the sugammadex sodium intermediate gamma-ICD; and the preparation method disclosed by the invention has the beneficial effects that the operation is convenient, the reaction conditions are mild and controllable, the reaction stability is high, and the reaction product is high in yield and purity.

Description

technical field [0001] The invention relates to the field of drug impurity synthesis, in particular to a sugammadex sodium intermediate diphenyl phosphate derivative impurity and a preparation method thereof. Background technique [0002] Sugammadex Sodium, chemical name 6-perdeoxy-6-perfect (2-carboxyethyl) thio-γ-cyclodextrin sodium salt, trade name Bridion, CAS: 343306-71- 8. The structural formula is as follows: [0003] [0004] Sugammadex sodium is a selective relaxation agent used to reverse the effect of muscle relaxants rocuronium bromide or vecuronium bromide, which was first discovered by the Dutch company Organon Biosciences. On July 25, 2008, the European Medicines Agency approved sugammadex sodium for marketing in Europe. On October 20, 2010, sugammadex sodium was approved for marketing in Japan. In November 2015, the FDA approved the drug for marketing in the United States. At present, CFDA has approved the listing of sugammadex sodium in China on April ...
