Document Type and Number:
WIPO Patent Application WO/2024/002353
Kind Code:
A1
Abstract:
Provided are a pharmaceutically acceptable salt and a crystal form of a nitrogen-containing bridge heterocyclic derivative, and a method for preparing same. Specifically provided are different salt forms and crystal forms of salts of 4-((1S,3S,5R)-3-ethoxy-8-((5-methoxy-7-methyl-1H-indol-4-yl)methyl)-8-azabicyclo[3.2.1]octyl-1-yl)benzoic acid, and a method for preparing same. The provided crystal forms of salts of 4-((1S,3S,5R)-3-ethoxy-8-((5-methoxy-7-methyl-1H-indol-4-yl)methyl)-8-azabicyclo[3.2.1]octyl-1-yl)benzoic acid have good stability and can be better used for clinical treatment.
