Abstract
The invention relates to crystalline free base forms of biphenyl-2-ylcarbamic acid 1-[2-(4-{[(R)-2-(3-formylamino-4-hydroxyphenyl)-2-hydroxyethylamino]methyl}-2,5-dimethylphenylcarbamoyl)ethyl]piperidin-4-yl ester or a solvate thereof. This invention also relates to pharmaceutical compositions containing or prepared from such crystalline forms; processes and intermediates useful for preparing such crystalline forms; and methods of using such crystalline forms to, for example, treat a pulmonary disorder.
