This invention provides the compounds of formula (I), or its a pharmaceutically acceptable ester or amide of such compound, or a pharmaceutically acceptable salt thereof, wherein X1 is NH; R1, R2, R4 through R6 and R7 through R11 are all hydrogen; R3 is hydroxy; X2 and X3 are methylene; X4 is a bond; and X5 is a carbon atom, and the like. These compounds have ORLI -receptor antagonist activity; and therefore, are useful to treat diseases or conditions such as pain, various CNS diseases etc.
A practical and chromatography-free synthetic process to selective M1 and M4muscarinic acetylcholine receptors agonist was developed and demonstrated on a several hundred gram scale. The key feature of this route is N,N-dimethylcarbamoylation of the anilinic nitrogen on the spiro 7-azaindoline structure via intermolecular migration of the N,N-dimethylcarbamoyl group. The resulting compound 1 was prepared
