Patent ID: 7148226

Claim:
Compounds of formula (4), wherein: R 1 is cyclopentyl; R 3 is —(CR 8 R 9 ) t (4–10 membered heterocyclic), wherein t is an integer from 0 to 5, and the heterocyclic moiety is optionally substituted by 1 to 5 R 4 groups; each R 4 is independently chosen from halo, C 1 –C 10 alkyl, and R 6 —O—, and each C 1 –C 10 alkyl may be optionally substituted by at least one substituent chosen from halo, trifluoromethyl, trifluoromethoxy, C 1 –C 10 alkyl, and cyano; or when two adjacent R 4 groups are both C 1 –C 10 alkyl, they, together with the atoms to which they are attached, form a 3- to 7-membered ring, wherein in said ring any carbon atom may be replaced by a heteroatom chosen from N, O, and S, provided that two adjacent carbons are not both replaced by heteroatoms; R 8 is hydrogen or C 1 –C 10 alkyl; R 8 and R 9 are hydrogen; z is an integer from 1 to 5; and y is an integer from 0 to 5.
