Document Type and Number:
WIPO Patent Application WO/2017/194002
Kind Code:
A1
Abstract:
Disclosed are a crystal form of Brexpiprazole and a preparation method therefor. The X-ray powder diffraction pattern, which is detected with Cu-K α radiation, of the crystal form of Brexpiprazole has characteristic peaks at the positions where 2θ is about 9.1±0.2, 15.2±0.2, 15.7±0.2, 17.6±0.2, 18.1±0.2, and 24.4±0.2.
