Patent ID: 7084165

Claim:
A compound of the formula wherein phenyl ring A and phenyl ring B can each, independently, be replaced by a naphthyl group, and wherein when phenyl ring A is replaced by a naphthyl group, the ethereal oxygen of structure I and the carbon to which R 3 , R 4 and NR 1 R 2 are attached, are attached to adjacent ring carbon atoms of the naphthyl group and neither of said adjacent ring carbon atoms is also adjacent to a fused ring carbon atom of said naphthyl group; n and m are, selected, independently, from one, two and three; R 1 is selected from hydrogen, (C 2 –C 4 )alkyl, (C 2 –C 4 )alkenyl, and (C 2 –C 4 )alkynyl; R 2 and R 3 , together with the nitrogen to which R 2 is attached and the carbon to which R 3 is attached, form a five membered saturated ring containing one or two heteroatoms, including the nitrogen to which R 2 is attached, wherein the second heteroatom, when present, is selected from oxygen, nitrogen and sulfur, with the proviso that said ring can not contain two adjacent oxygen atoms or two adjacent sulfur atoms, and wherein said ring may optionally be substituted at available binding sites with from one to three substituents selected, independently, from hydroxy and (C 1 –C 6 )alkyl; R 4 is selected from hydrogen and (C 1 –C 4 ) alkyl optionally substituted with from one to three fluorine atoms; each X is selected, independently, from hydrogen, halo, chloro, fluoro, bromo or iodo, (C 1 –C 4 )alkyl optionally substituted with from one to three fluorine atoms, (C 1 –C 4 )alkoxy optionally substituted with from one to three fluorine atoms, cyano, nitro, amino, (C 1 –C 4 )alkylamino, di-[(C 1 –C 4 )alkyl]amino, NR 5 (C═O)(C 1 –C 4 )alkyl, SO 2 NR 5 R 6 and SO p (C 1 –C 6 )alkyl, wherein R 5 and R 6 are selected, independently, from hydrogen and (C 1 –C 6 )alkyl, and p is zero, one or two; and each Y is selected, independently, from hydrogen, (C 1 –C 6 )alkyl and halo; with the proviso that: (a) no more than one of NR 1 R 2 , CR 3 R 4 and R 2 NCR 3 can form a ring; and (b) at least one X must be other than hydrogen when (i) R 3 and R 4 are both hydrogen, (ii) R 1 and R 2 are selected, independently, from hydrogen and (C 1 –C 4 )alkyl, and (iii) ring B is mono- or disubstituted with, respectively, one or two halo groups; or a pharmaceutically acceptable salt thereof.
