Diclosed is a maleate salt of 4-((4-fluoro-2-methyl-1H-indol-5-yl)oxy)-6-methoxy-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline, in the crystalline form Form A, wherein said salt has an X-ray powder diffraction pattern with at least one specific peak at about 2-theta = 21.5° and 16.4°. Also diclosed is a maleate salt of 4-((4-fluoro-2-methyl-1H-indol-5-yl)oxy)-6-methoxy-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline, in the crystalline form Form B, wherein said salt has an X-ray powder diffraction pattern with at least one specific peak at about 2-theta = 24.2° and 22.7°. |
