Patent ID: 8569339

Claim:
A compound of the formula I wherein: A is a 5- or 6-membered aryl, heteroaryl or heterocyclyl group; B is a 5-7 membered heterocyclyl group containing one nitrogen, wherein one carbon of the heterocyclyl group is optionally substituted with an oxo group, or B is a 5-membered heteroaryl group containing at least 2 nitrogens; R 1 and R 2 are independently selected from H, C 1-4 alkyl, C 3-6 cycloalkyl, tetrahydropyranyl, —CF 3 , —CH 2 CF 3 and —CH 2 CH 2 CO 2 H; R 3 is selected from H and —CH 3 ; R 4 is selected from H, C 1-6 alkyl, C 3-7 cycloalkyl, —C(O)C 1-6 alkyl, —CH 2 CF 3 , —SO 2 C 1-6 alkyl, —SO 2 (CH 2 ) 1-3 CO 2 H, —CO 2 C 1-4 alkyl, heterocyclyl, aryl, heteroaryl, —(C 0-2 alkyl)heterocyclyl, —(C 1-2 alkyl)aryl and —(C 1-2 alkyl)heteroaryl, wherein said heterocyclyl is selected from tetrahydrofuranyl, azetidinyl, pyrrolidinyl, pyranyl, tetrahydropyranyl, dioxanyl, thiomorpholinyl, 1,1-dioxo-1λ 6 -thiomorpholinyl, morpholinyl, piperidinyl, piperazinyl, and azepinyl, and said heterocyclyl, cycloalkyl, aryl and heteroaryl are optionally substituted with one to two groups independently selected from C 1-3 alkyl, —CF 3 , and halogen, or R 4 is optionally not present when B is a heteroaryl group; R 5 is selected from H, —C 1-3 alkyl, —OCH 3 , —CF 3 , —CN and Cl; and R 6 is selected from H and CH 3 ; provided that R 5 and R 6 are not both H; or a salt thereof.
