Vitreous form of 8-(3-(N-((E)-3-(6-acetamidopyridin-3-yl)-acryloylglycyl)-N-methylamino)-2,6-dichlorobenzyloxy)-2-methylquinoline

摘要

This invention relates to a vitreous form of 8-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methylquinoline (FR173657). This vitreous form has good solid stability and, therefor, is useful for producing and supplying FR173657 products whose quality is stable enough to be suitable for medicines.
