Abstract
The invention relates to a new crystalline form of the methanesulfonic acid addition salt of 4-(4-methylpiperazin-1-yl-methyl)-N-[4-methyl-3-(4-pyridin-3-yl)pyrimidin-2-ylamino)phenyl]-benzamide of formula I, which may be used for example for tumour therapy.
Claims
exact text as granted — not AI-modified1. A crystalline form of the monomethanesulfonic acid addition salt of a compound of formula I,
having non-needle-shaped crystals.
2. A crystalline form according to claim 1 of the methanesulfonic acid addition salt of a compound of formula I, which comprises at least 95% by weight crystals of the β-modification.
3. A crystalline form according to claim 1 of the methanesulfonic acid addition salt of a compound of formula I, which shows on X-ray diffraction a peak at an angle of refraction 2theta of 20°, said peak having a relative line intensity of about 65% as compared to the most intense line in the diagram.
4. A pharmaceutical composition, comprising the crystal form according to claim 1 of the methanesulfonic acid addition salt of a compound of formula I and a pharmaceutically acceptable carrier.Cited by (0)
