Title:
METHOD FOR PRODUCING AMINOAZIDE COMPOUND, DIAMINE COMPOUND, AND EDOXABAN
Document Type and Number:
WIPO Patent Application WO/2024/053350
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing an aminoazide compound and a diamine compound in which the formation of undesired diastereomers is inhibited and which has good diastereoselectivity. Provided is a method for producing an aminoazide compound represented by formula (1), said method being characterized by comprising an azidation step for causing diphenylphosphoryl azide, a phosphine compound, and an azo compound to act on an amino alcohol compound represented by formula (2).
