MONOSEBACATE OF PYRAZOLE DERIVATIVE

摘要

The present invention provides a novel form of 3-(3-{4-[3-(²-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-( - D-glucopyranosyloxy)-5-isopropyl-1H-pyrazol-4-ylmethyl]-3-methylphenoxy}pr opylamino)-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.
