Patent ID: 8329707

Claim:
A compound of formula (I) or a pharmaceutically acceptable salt thereof: wherein R 1 is lower alkyl, halogeno-lower alkyl, or cycloalkyl, R 2 is cycloalkyl, R 3 is halogen, lower alkyl, halogeno-lower alkyl, —OR 0 , or —O-halogeno-lower alkyl, R 0 independently represents —H or lower alkyl, Ring A is pyrazinyl which may be substituted with up to five moieties independently selected from the group consisting of halogen, cyano, lower alkyl which may be substituted with —OR 0 , halogen-lower alkyl, lower alkylene-OC(O)R 0 , lower alkylene-O-hetero ring group, —OR 0 , —O-halogeno-lower alkyl, —O-lower alkylene-OR 0 , —S(O) p -lower alkyl, —S(O) p -lower alkylene-OR 0 , —C(O)R 0 , —C(O)-lower alkylene-OR 0 , —CO 2 R 0 , lower alkylene-CO 2 R 0 , —O-lower alkylene-CO 2 R 0 , —S(O) p -lower alkylene-CO 2 R 0 , —C(O)N(R 0 ) 2 and a hetero ring group, wherein the hetero ring group may be substituted with up to five moieties independently selected from the group consisting of halogen, lower alkyl, halogeno-lower alkyl, —OR 0 , —O-halogeno-lower alkyl and oxo, Ring B is aryl or heteroaryl which may each be substituted with up to five moieties independently selected from the group consisting of halogen, lower alkyl, halogeno-lower alkyl, —OR 0 , and —O-halogeno-lower alkyl, or wherein represents formula (I), X independently represents —C(R 4 )(R 5 )—, —C(O)—, —O—, —S(O) p —, or —N(R 0 )—, m is 2, 3, 4, 5, 6 or 7, R 4 and R 5 independently represent —H, halogen, lower alkyl, halogeno-lower alkyl, —OR 0 , or —O-halogeno-lower alkyl, and n and p independently represent 0, 1 or 2, provided that means a single bond or a double bond.
