Aromatic azole compounds such as 2-(4-aminophenyl)-5-amino-benzimidazole are prepared in an organic sulfonic acid solvent instead of polyphosphoric acid. This allows recovery and recycle of the solvent and avoids the handling and environmental concerns resulting from the use of polyphosphoric acid. The resulting compounds find use in the pharmaceutical industry, as anticorrosion agents, and as precursors for high-performance fibers having high strength, stiffness, and flame resistance.
Compositions and methods and are provided for treating disorders associated with compromised vasculostasis. Invention methods and compositions are useful for treating a variety of disorders including for example, stroke, myocardial infarction, cancer, ischemia/reperfusion injury, autoimmune diseases such as rheumatoid arthritis, eye diseases such as retinopathies or macular degeneration or other vitreoretinal diseases, inflammatory diseases, vascular leakage syndrome, edema, transplant rejection, adult/acute respiratory distress syndrome (ARDS), and the like.

A method of treating a mammal comprises administering to a mammal an effective amount to provide a desired therapeutic effect in the mammal of a compound selected from the group consisting of those having the formula: ##STR1## , pharmaceutically acceptable acid addition salts thereof and mixtures thereof, wherein R.sub.1 and R.sub.4 are independently selected from the group consisting of H and alkyl radicals having 1 to 4 carbon atoms; the R.sub.2 s are independently selected from H or alkyl radicals having 1 to 4 carbon atoms or are, together, oxo; the R.sub.3 s are independently selected from H or alkyl radicals having 1 to 4 carbon atoms or are, together, oxo; the 2-imidazolin-2-ylamino group may be in any of the 5-, 6, 7- or 8- positions of the quinoxaline nucleus; and R.sub.5, R.sub.6 and R.sub.7 each is located in one of the remaining 5-, 6-, 7- or 8- positions of the quinoxaline nucleus and is independently selected from the group consisting of Cl, Br, H and alkyl radicals having 1 to 3 carbon atoms. Such compounds, when administered to a mammal, provide desired therapeutic effects, such as constriction of one or more blood vessels and decongestion of one or more nasal passages.
