Abstract:
1. A crystalline 5-[4-[2-(N-methyl-N-(2-pyridyl)amino)ethoxy]benzyl]thiazolidine-2,4-dione maleic acid salt which provides at least one of: (i) an infra red spectrum containing peaks at 1752, 1546, 1154, 621, and 602 cm (ii) a Raman spectrum containing peaks at 1751, 1243 and 602 cm (iii) a solid-state (iv) an X-ray powder diffraction pattern which gives calculated lattice spacings of 6.46, 5.39, 4.83, 4.68, 3.71, 3.63, 3.58, and 3.48 Angstroms.
