One-Step Conversion of Azine N-Oxides to α-1,2,4-Triazolo-, 1,2,3-Triazolo, Imidazolo-, and Pyrazoloheteroarenes
摘要:
Pyridine, quinoline, isoquinoline, azaindole, and pyrimidine N-oxides were converted to their alpha-triazole and alpha-diazole derivatives by treatment with the corresponding p-toluenesulfonylazoles and Hunig's base at elevated temperatures.
The invention provides certain 3-pyridyl carboxamide-containing compounds of the Formula (I) (I) or pharmaceutically acceptable salts thereof, wherein A and B are as defined herein. The invention also provides pharmaceutical compositions comprising such compounds, and methods of using the compounds for treating diseases or conditions mediated by Spleen Tyrosine Kinase (Syk) kinase.
