    • In a benzodiazepine derivative and a method of producing the derivative, isatoic anhydride or 5-chloroisatoic anhydride is reacted with amino acid ester hydrochloride for conducting a simple cyclization to obtain a produce with a low percentage of by-product directly without requiring the complicated separation and purification processes of column chromatography, and a chlorine-containing structure of the structure can improve the lipo-solubility and chlorine ion permeability and allow a functional group of a radioisotope to be modified to maximize the effects of the pharmacological properties such as the sedative, anticonvulsant and anti-spasmodic effects on the central nervous system or the benzodiazepine derivative can be used as a contrast agent of the system with excellent effects on applications.
    • 在苯并二氮杂衍生物和衍生物的制造方法中,将丙酸酐或5-氯代酸酐与氨基酸酯盐酸盐反应,进行简单的环化,直接得到副产物的百分比低的产物,无需复杂的分离, 柱层析的纯化方法和结构的含氯结构可以改善脂溶性和氯离子渗透性,并允许改性放射性同位素的官能团以最大化药理学性质的影响,例如镇静剂,抗惊厥药 对中枢神经系统或苯并二氮杂衍生物的抗痉挛作用可用作系统的造影剂,对应用效果优异。
