Patent ID: 7897634

Claim:
A compound of the formulae: where X is O, y is 0, 1 or 2; n is 0 or 1; q is 0, 1, or 2; R 1 and R 2 are independently selected from the group consisting of (C 1 -C 5 )alkyl and (C 3 -C 6 )cycloalkyl; or where X is O, R 1 and R 2 taken together with the nitrogen to which they are attached form a 5-7 member heterocyclic ring system with 0 or 1 additional hetero atoms selected from O, S, and NR 6 , wherein the resulting ring may optionally be substituted with 1-3 (C 1 -C 6 )alkyl or (C 3 -C 6 )cycloalkyl groups; R 3 is 0-2 of groups selected from halogen, (C 1 -C 8 )alkyl, (C 1 -C 8 )alkoxy, (C 3 -C 7 )cycloalkyl, (C 3 -C 7 )cycloalkyl-(C 1 -C 6 )alkyl, heterocycloalkyl containing 1-3 hetero atoms selected from O and S, and (C 1 -C 5 )alkyl-O—(C 1 -C 5 )alkyl; R 4 and R 6 are independently selected from (C 1 -C 8 )alkyl, (C 1 -C 8 )alkoxy, (C 3 -C 7 )cycloalkyl, (C 3 -C 7 )cycloalkyl-(C 1 -C 6 )alkyl, heterocycloalkyl containing 1-3 hetero atoms selected from O, S, and NH 2 , (C 1 -C 5 )alkyl-O—(C 1 -C 5 )alkyl, (C 1 -C 5 )alkyl-aryl, and CF 3 ; R 5 is selected from the group consisting of hydrogen, (C 1 -C 8 )alkyl, aryl, (C 1 -C 5 )alkyl-O—(C 1 -C 5 )alkyl, and (C 1 -C 5 )alkyl-aryl; or R 5 and R 4 and the atoms to which they are attached form a fused 5-6 member saturated carbocyclic ring or a fused 10 member bi-cyclic ring system; or R 5 and R 6 and the atoms to which they are attached form a fused 5-6 member saturated carbocyclic ring or a fused 10 member bi-cyclic ring system; or R 5 and R 4 and the atoms to which they are attached form a fused 5-6 member saturated carbocyclic ring to which a 6 member aromatic ring is fused; or R 5 and R 6 and the atoms to which they are attached form a fused 5-6 member saturated carbocyclic ring to which a 6 member aromatic ring is fused; or R 5 and R 6 and the atoms to which they are attached form a fused benzothiophene or fused benzofuran ring system; or a pharmaceutically acceptable salt thereof.
