Zusammenfassung:	The present invention relates to a preparation method of a novel vascular leakage blocker with a high yield. The preparation method is easy to react and more productive and economical than the conventional method by using an intermediate that can easily remove impurities generated during the reaction. In addition, the preparation method can produce a novel vascular leakage blocker with a high yield by using a new reagent that has not been previously used in the step of generating an isomer, and is very advantageous in producing a high-quality active pharmaceutical ingredient.
