Patent ID: 8450314

Claim:
A compound of formula (IA) or (IB) or a pharmaceutically acceptable salt thereof, wherein: R 2a , R 2b , and R 2c are independently selected from H, halogen and C 1 -C 6 alkyl; Y is —O— or —S(O) p — wherein p is 0, 1 or 2; and R 1 is a radical of formula (IIA), (IIB), (IIC), or (IID) wherein m is 0 or 1, T is —N or —CH, R 3 is H or F, R 4 is —CH 3 ; —C 2 H 5 ; —CH 2 OH, CH 2 SCH 3 ; —SCH 3 , or —SC 2 H 5 , R 5 is —CH 3 or —C 2 H 5 ; R 6 is H, or represents one or more substituents, each independently selected from the group consisting of a C 1 -C 6 alkyl, hydroxy, a halogen, a radical of formula (IIIA), a radical of formula (IIIB), and a radical of formula (IIIC): wherein R 61a and R 61b are independently H or C 1 -C 6 alkyl, or R 61a and R 61b , taken together with the nitrogen to which they are attached, form a 6-membered heterocyclic ring optionally comprising a further heteroatom selected from the group consisting of N and O; and p is 1 or 2.
