Title:
CRYSTAL FORM OF 4-ISOPROPYLPHENYL GLUCITOL COMPOUND AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/023598
Kind Code:
A1
Abstract:
Provided are a highly stable crystal of (1S)-1,5-anhydro-1-[5-(4-{(1E)-4-[(1-{[2-(dimethylamino)- ethyl]amino}-2-methyl-1-oxopropan-2-yl)amino]-3,3-dimethyl-4-oxobut-1-en-1-yl}benzyl)-2-methoxy-4-(propan-2-yl)phenyl]-D-glucitol and a process for producing the crystal. Specifically provided are an ethanol solvate having the physical properties mentioned below and another multiple crystal forms derived from the ethanol solvate: (a) peaks appear at 2θ = 5.9˚, 17.1˚, 17.6˚ and 21.5˚ in powder X-ray diffraction (Cu-Kα); (b) characteristic absorption bands appear at 3538 cm-1, 3357 cm-1, 2964 cm-1, 1673 cm-1, 1634 cm-1 and 1505 cm-1 in infrared absorption spectra; and (c) the melting point is about 111˚C.
