    • The problem to be solved is to provide an important intermediate for production of an FXa inhibitor. The solution thereto is a method for industrially producing a compound (1) or a compound (4), comprising: [Step 1]: adding a quaternary ammonium salt and a metal azide salt to water to prepare an aqueous solution of an azidification reagent complex comprising quaternary ammonium salt-metal azide salt, and subsequently dehydrating the aqueous solution using an aromatic hydrocarbon solvent to form a mixed solution of the azidification reagent complex comprising quaternary ammonium salt-metal azide salt and the aromatic hydrocarbon solvent with a water content of 0.2% or less; and [Step 2]: adding, to the mixed solution prepared in [Step 1], a compound (2) wherein L represents a leaving group.
    • 要解决的问题是提供生产FXa抑制剂的重要中间体。 其溶液是工业上制备化合物(1)或化合物(4)的方法,其包括:[步骤1]:将季铵盐和金属叠氮化物盐加入到水中以制备叠氮化试剂络合物的水溶液 包括季铵盐 - 金属叠氮化物盐,然后使用芳族烃溶剂使水溶液脱水以形成包含季铵盐 - 金属叠氮化物盐和芳族烃溶剂的叠氮化试剂络合物的水含量为0.2% 或更少; 和[步骤2]:向[步骤1]中制备的混合溶液中加入其中L表示离去基团的化合物(2)。
