1‐(ω‐Bromoalkyl)indazoles undergo a facile thermal intramolecular cyclization reaction in the neat form. The reactions do not require the use of a solvent or base and proceed in quantitative yields. Moreover, their corresponding 2‐substituted isomers also cyclize affording the same cycloadducts. These reactions provide a facile entry into the synthesis of fused indazole ring systems with potential medicinal
Compounds and methods are provided for the treatment of disease conditions in which modification of cholinergic, especially muscarinic m1, m4, or both m1 and m4, receptor activity has a beneficial effect. In the method, an effective amount of a compound is administered to a patient in need of such treatment.
