Patent ID: 7776885

Claim:
A compound of the formula (I): wherein: Het represents A represents a methylene group; B represents a covalent bond or an alkylene group having from 1 to 5 carbon atoms, wherein when R 3 represents a heterocyclic group said alkylene group is optionally substituted by an oxo group; R 1 represents an isopropyl group or a cyclopentyl group; each R 2 independently represents a halogen atom or an alkyl group having from 1 to 4 carbon atoms; m is 0, 1, 2, 3, or 4; R 3 represents (i) a cycloalkyl group having from 3 to 8 carbon atoms, said cycloalkyl group being substituted by 1 to 5 substituents independently selected from the group consisting of substituents α 2 , or (ii) a heterocyclic group having from 3 to 8 atoms, said heterocyclic group being unsubstituted or substituted by 1 to 5 substituents independently selected from the group consisting of substituents β; wherein said substituents α 2 are hydroxy, amino, hydroxy-substituted alkyl having from 1 to 4 carbon atoms, and alkoxy having from 1 to 4 carbon atoms; and wherein said substituents β are hydroxy, hydroxy-substituted alkyl having from 1 to 4 carbon atoms, amino, alkyl having from 1 to 4 carbon atoms, amino-substituted alkyl having from 1 to 4 carbon atoms, and carbamoyl; or a pharmaceutically acceptable salt thereof.
