[Problem] To provide a compound useful as an active ingredient of a pharmaceutical composition for treating 11β-hydroxysteroid dehydrogenase type 1-related diseases such as dementia, schizophrenia, depression, pain (particularly, neuropathic pain or fibromyalgia), diabetes (particularly, type II diabetes mellitus), insulin resistance and the like.
[Means for Solution] A bicyclic heterocyclic compound (the bicyclic heterocycle is formed when a cyclohexane ring is fused with a 5- to 6-membered monocyclic heterocycle that has only a nitrogen atom as a hetero atom) substituted with an acylamino group such as a (hetero)aroylamino group or the like or a pharmaceutically acceptable salt thereof was found to have an excellent selective inhibitory action against 11β-HSD1. Accordingly, the bicyclic heterocyclic compound of the present invention can be used for treating dementia, schizophrenia, depression, pain (particularly, neuropathic pain or fibromyalgia), diabetes (particularly, type II diabetes mellitus), insulin resistance, and the like.

been focussed on the design of highly efficientpalladiumprecatalysts to ensure the smooth formation of the active catalyst for metal‐mediated cross coupling reactions, we herein demonstrate that combining the bulky N‐heterocyclic carbene (NHC) 1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene (IPr) with cyclopalladated acetanilide as the optimal palladiumprecatalyst leads to superior catalytic activity
