Patent ID: 7300933

Claim:
An (R,R) or (S,S) diazabicyclic biaryl compound represented by Formula I or an enantiomer thereof or a mixture of its enantiomers, or a pharmaceutically acceptable salt thereof, wherein R represents hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkyl-alkyl or benzyl; and A represents a 5-membered aromatic monocyclic heterocyclic group selected from wherein X represents O or S and R′ represents hydrogen or alkyl, or A represents a 6-membered aromatic monocyclic heterocyclic group selected from which aromatic monocyclic heterocyclic group is optionally substituted with a substituent selected from the group consisting of halogen, CF 3 , CN, amino, and nitro, and B represents a 5-membered aromatic monocyctic heterocyclic group selected from wherein X represents O or S and R′ represents hydrogen or methyl, which aromatic group may optionally be substituted one or two times with substituents selected from the group consisting of halogen, CF 3 , CN, amino and nitro; or A represents a 5 -membered aromatic monocyclic heterocyclic group selected from wherein X represents O or S and R′ represents hydrogen or alkyl, and B represents a phenyl or naphthyl group, which phenyl or naphthyl group may optionally be substituted one or two times with substituents selected from the group consisting of alkyl, cycloalkyl, alkoxy, cyano-alkyl, halogen, CF 3 , OCF 3 , CN, amino, and nitro, or B represents a 5-membered aromatic monocyclic heterocyclic group selected from wherein X represents O or S and R′ represents hydrogen or methyl, which aromatic group may optionally be substituted one or two times with substituents selected from the group consisting of halogen, CF 3 , CN, amino and nitro.
