专利号:US-2025011348-A1 优先权日:2023-06-13 标题:Synthesis Process of X-IPM, Stable Crystal Form and Application Thereof 发明人:DUAN JIANXIN; LU ZHAOQIANG; CAI XIAOHONG; FAN JINWEI; QIN WEI; HUANG QUNHUI; ZHANG YANJUN; CHEN WEISU 权利人:ASCENTAWITS PHARMACEUTICALS LTD 摘要:The present application relates to a new method for synthesizing isophosphoramide nitrogen mustard (X-IPM) that is suitable for industrialized production, involves fewer types of solvents, and leads to stable products with high yield. This method is charazterized mainly by the batchwise addition of M (e.g., M is R3N with R being ethyl; i.e., M is triethylamine) and the specific post-reaction treatment, which make it possible for the reaction to fully proceed, lead to products with less impurities, high yield and relatively stable properties, and can lead to stable crystallized substances with specific crystal structures. The present application also relates to stable crystal forms of the isophosphoramide nitrogen mustard (X-IPM) prepared by the aforementioned method, and use of the same as reactants for the synthesis of aziridine structure-containing compounds.

专利号:US-2024425461-A1 优先权日:2023-06-13 标题 :Preparation process of intermediate, synthesis process of amino imidazole carboxylate ester and hplc purity measure method 发明人:DUAN JIANXIN; LU ZHAOQIANG; FAN JINWEI; HUANG QUNHUI; ZHANG YANJUN; CHEN WEISU; QIN WEI 权利人:ASCENTAWITS PHARMACEUTICALS LTD 摘要:This invention relates to a process for preparing an intermediate of aminoimidazole carboxylate, a process for synthesizing aminoimidazole carboxylate and an HPLC method for determining purity. The process of preparing the intermediate of aminoimidazole carboxylate comprises subjecting a compound of formula I-2 and a formate as the reactants to a first-step reaction in a benzene solvent and at a temperature of −5° C.−5° C., with the addition of a solution of sodium alkoxide in such a way that the temperature of the reaction solution is not higher than 5° C., to obtain the intermediate of aminoimidazole carboxylate or a mixture comprising a compound of formula I-3, i.e., the intermediate of aminoimidazole carboxylate. By using a sodium alkoxide reagent, as a comparatively safe alternative to NaH and potassium tert-butoxide which are prone to cause fire hazards or explosions and are not suitable for use in large-scale production, the process of the present application can ensure smooth progression of the reaction to the product and effectively improve the overall safety of the reaction without noticeably impairing the reaction efficiency.
