Title:
SALTS OF COMPOUND, CRYSTALLINE FORMS THEREOF, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/253875
Kind Code:
A1
Abstract:
Disclosed are a fumaric acid salt, a maleic acid salt, an adipic acid salt, a succinic acid salt, a plurality of crystalline forms of a compound 5-fluorine-4-(7'-fluorine-2'-methyl spiro [cyclopentane-1,3'-indol]-5'-yl)-nitrogen-(5-(1-methylpiperidine-4-yl)pyridine-2-yl)pyrimidine-2-amine, a preparation method therefor and an application thereof. It has been proved that the salts or the crystalline forms thereof can replace 5-fluorine-4-(7'-fluorine-2'-methyl spiro [cyclopentane-1,3'-indol]-5'-yl)-nitrogen-(5-(1-methylpiperidine-4-yl)pyridine-2-yl)pyrimidine-2-amine better, overcome the defects thereof such as the solubility, high risk of food effect and stability, and have low hygroscopicity and great application value.
