Patent ID: 8044070

Claim:
A compound of the formula (I): wherein: R is selected from the group consisting of: a linear or branched C 2-6 alkyl group, or a cycloalkyl group having from 3 to 9 carbon atoms, which is unsubstituted or substituted with a group selected from the group consisting of: a cyano group; a hydroxyl group; a lower alkyl group optionally substituted with a hydroxyl group, a halogen atom or an amino group; a lower alkoxy group optionally substituted with a halogen atom; a halogen atom; a mono-lower alkylaminocarbonyloxy group; a di-lower alkylaminocarbonyloxy group; a mono-lower alkylcarbamoyl group; a di-lower alkylcarbamoyl group; a carbamoyl group; a cycloalkyliminocarbonyl group; and a trifluoromethyl group, Y is selected from the group consisting of: (1) a phenyl group; which is unsubstituted or substituted with 1 or 2 substituents selected from the group consisting of: a hydroxyl group; a lower alkyl group optionally substituted with a hydroxy group, a halogen atom or an amino group; a lower alkoxy group optionally substituted with a halogen atom; a lower alkylsulfonyl group; a cyclo-lower alkylsulfonyl group; a halogen atom; a mono-lower alkylaminocarbonyloxy group; a di-lower alkylaminocarbonyloxy group; a mono-lower alkylcarbamoyl group; a di-lower alkylcarbamoyl group; a cycloalkyliminocarbamoyl group; a lactam ring; a mono-lower alkylamino group; a di-lower alkylamino group; an alkanoyl group; an alkoxycarbonylamino group wherein the nitrogen atom optionally substituted with a lower alkyl group; an alkanoylamino group wherein the nitrogen atom is optionally substituted with a lower alkyl group; and an alkylsulfonylamino group wherein the nitrogen atom is optionally substituted with a lower alkyl group; or (2) a group of the formula (Q1-1): wherein R 7 represents a hydrogen atom, a lower alkyl group, a cyclo-lower alkyl group, a halo-lower alkyl group, or an aralkyl group; or a pharmaceutically acceptable salt thereof.
