general alkylation of heterocycles using a simple palladium catalyst is reported. Most classes of heterocycles, including indoles and pyridines, efficiently coupled with unactivated secondary and tertiary alkylhalides. An alkyl radical addition to neutral heteroarenes is most likely involved.
The invention relates to novel compounds having the general formula (I), and which compounds are useful to treat a disorder or disease characterized by bronchoconstriction, e.g. COPD and asthma.
