Compounds of formula (I) are inhibitors of fatty acid amide hydrolase, (FAAH), and which are useful in the treatment of diseases or medical conditions which benefit from inhibition of FAAH activity, such as anxiety, depression pain, inflammation, and eating, sleep, neurodegenerative and movement disorders: n nAr 1 is optionally substituted phenyl or optionally substituted monocyclic heteroaryl having 5 or 6 ring atoms; Ar 2 is optionally substituted phenyl, optionally substituted monocyclic heteroaryl having 5 or 6 ring atoms or optionally substituted fused bicyclic heteroaryl having 5 or 6 ring atoms in each fused ring; and Ar 3 is a divalent radical selected from optionally substituted phenylene and optionally substituted monocyclic heteroarylene radicals having 5 or 6 ring atoms. |
