Title:
METHOD FOR PRODUCING DIHYDROPYRIDAZINE-3,5-DIONE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2022/260062
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method that is for producing p-toluenesulfonate of 7-(2,3-difluoro-4-(2-((2-methoxyethyl)(methyl)amino)ethoxy)benzyl)-10-hydroxy-6-methy-N-(4-methyl-2-(6-methylpyrimidine-4-yl)phenyl)-8-oxo-6,7-diazaspiro[4.5]deca-9-en-9-carboxamide which is industrially preferable and that makes it possible to obtain a target product more easily and more inexpensively than conventional methods. For the present invention, a method was found which makes it possible to efficiently obtain a target product via a step for obtaining a wet powder of p-toluenesulfonate of 7-(2,3-difluoro-4-(2-((2-methoxyethyl)(methyl)amino)ethoxy)benzyl)-10-hydroxy-6-methy-N-(4-methyl-2-(6-methylpyrimidine-4-yl)phenyl)-8-oxo-6,7-diazaspiro[4.5]deca-9-en-9-carboxamide and also a step for drying the wet powder.
