Patent ID: 7662816

Claim:
A compound having the structural formula or a pharmaceutically acceptable salt thereof, wherein R 1 is R is —C(O)—N(R 27 )(R 28 ); R 2 is H, alkyl, phenyl, or benzyl, wherein said phenyl and said benzyl are optionally unsusbtituted or substituted by from 1 to 5 independently selected R 32 groups; R 3 is H or alkyl; R 4 is H or alkyl; R 5 is H or alkyl; R 14 is 1 to 4 substituents independently selected from the group consisting of H, alkyl, halo, —CN, and haloalkyl; R 27 and R 28 are independently selected from alkyl; or R 27 and R 28 together with the nitrogen to which they are attached, form an unsubstituted 3-7 membered heterocycloalkyl ring, or a 3-7 membered heterocycloalkyl ring substituted by 1-3 substituents independently selected from the group consisting of alkyl, alkoxyalkyl, haloalkoxyalkyl, cycloalkyl, cycloalkylalkyl and cycloalkyl-alkoxyalkyl; R 6 and R 7 are each independently selected from the group consisting of H and alkyl, or R 6 and R 7 , together with the ring carbon to which they are attached, form —C(O)—; R 8 R 9 are each independently selected from the group consisting of H and alkyl, or R 8 and R 9 , together with the ring carbon to which they are attached, form —C(O)—; R 12 and R 13 are each independently selected from the group consisting of H and alkyl, wherein said alkyl is unsubstituted or substituted by from 1 to 5 independently selected R 32 groups, or R 12 and R 13 , together with the ring carbon to which they are attached, form —C(O)—; R 18 is H, alkyl, phenyl, phenylalkyl, pyridyl, oxazolyl, pyrazinyl, thienyl, imidazolyl, pyridylalkyl, oxazolylalkyl, pyrazinylalkyl, thienylalkyl, or imidazolylalkyl, wherein said alkyl, said phenyl, said phenylalkyl, said pyridyl, said oxazolyl, said pyrazinyl, said thienyl, said imidazolyl, said pyridylalkyl, said oxazolylalkyl, said pyrazinylalkyl, said thienylalkyl, and said imidazolylalkyl, are each unsubstituted or substituted by from 1 to 4 independently selected R 32 groups; R 19 is H, alkyl, phenyl, phenylalkyl, pyridyl, oxazolyl, pyrazinyl, thienyl, imidazolyl, pyridylalkyl, oxazolylalkyl, pyrazinylalkyl, thienylalkyl, or imidazolylalkyl, —SOR 18 , —SO 2 R 18 or —CN, wherein said alkyl, said phenyl, said phenylalkyl, said pyridyl, said oxazolyl, said pyrazinyl, said thienyl, said imidazolyl, said pyridylalkyl, said oxazolylalkyl, said pyrazinylalkyl, said thienylalkyl, and said imidazolylalkyl, are each unsubstituted or substituted by from 1 to 4 independently selected R 32 groups; and each R 32 is independently selected from the group consisting of halo, alkyl, alkoxy, —OH, phenyl, —NO 2 , —CN, and haloalkyl, or two R 32 groups on the same ring carbon atom are taken together to form ═O.
