    摘要: Crystals of (1S,2S,3R,4S,5R,8R,9S,10R,13S)-4-acetoxy-2 -benzoyloxy-9,10-[(1S)-2-(dimethylamino)ethylidenedioxy]-5,20-epoxy-1-hydroxytax-11-en-13-yl (2R,3S)-3-(tert-butoxy- carbonylamino)-3-(3-fluoro-2-pyridyl)-2-hydroxypropionate, which exhibit in the powder X-ray diffraction pattern characteristic peaks at diffraction angles (2θ) of 6.2°, 10.3°, 10.7°, 11.4°, and 12.0°; and a process for production of the crystals which comprises the step of conducting crystallization by the use of an organic solvent selected from among ketones, nitriles and mixtures of both or a mixture of the organic solvent with water.

    摘要: Substantially nonhygroscopic anhydrous crystals of compounds represented by the general formula: R2-CH2CONH-R1 (wherein R1 represents (un)substituted pyridyl or (un)substituted phenyl; and R2 represents (un)substituted 2-oxo-1-pyrrolidinyl). Drying the hydrous crystals of the above compounds at a temperature of 80 °C or above under reduced pressure yields the corresponding anhydrous crystals with a weight gain of at most 1 % caused by moisture absorption after storage at a relative humidity of 83 % and a temperature of 25 °C for 30 days. Medicines containing the above compounds in the form of anhydrous crystals are uniform in the active ingredient content.
