The present invention provides a novel form of 3-(3-{4-[3-(.beta.-D-gluco- pyranosyloxy)-5-isopropyl-1H-pyrazol-4-ylmethyl]-3-methylphenoxy}propylamino)- 2,2-dimethylpropionamide with improved storage stability. Since bis[3-(3-{4-[3- (.beta.-D- glucopyranosyloxy)-5-isopropyl-1H-pyrazol-4-ylmethyl]-3-methylphenoxy}propyl- amino)-2,2-dimethylpropionamide] monosebacate has extremely excellent storage stability, it is useful as a drug substance. Furthermore, it shows an extremely good crystalline property and can be purified by a convenient method, and therefore is suitable for the industrial preparation.
La présente invention concerne une nouvelle forme de 3-(3-{4-[3-(ß-D-glucopyranosyloxy)-5-isopropyl-1H-pyrazol-4-ylméthyl]-3-méthylphénoxy}-propylamino)-2,2-diméthylpropionamide dont la stabilité au stockage est améliorée. Etant donné que le monosébacate de bis[3-(3-{4-[3-(ß-D-glucopyranosyloxy)-5-isopropyl-1H-pyrazol-4-ylméthyl]-3-méthylphénoxy}-propylamino)-2,2-diméthylpropionamide présente une stabilité au stockage des plus excellentes, il est utile comme substance médicamenteuse pharmaceutique. En outre, il présente une excellente propriété de cristallinité et peut être purifié par un procédé simple, et est ainsi adapté à la production industrielle.
