摘要 |
Crystals of 5-[2-amino-4-(2-furyl)pyrimidin-5-yl]-1-methylpyridin-2(1H)-one having a diffraction peak at a diffraction angle (2&thetas;±0.2°) of 9.7° and/or 21.9° in a powder X-ray diffraction are suitable for an active ingredient of a preventing and therapeutic agent for diseases such as constipation. Crystals of 5-[2-amino-4-(2-furyl)pyrimidin-5-yl]-1-methylpyridin-2(1H)-one hydrate and amorphous 5-[2-amino-4-(2-furyl)pyrimidin-5-yl]-1-methylpyridin-2(1H)-one hydrate are also suitable for an active ingredient of a preventing and therapeutic agent for diseases such as constipation.
