Patent ID: 7855288

Claim:
A compound, or a pharmaceutically-acceptable acid addition salt thereof, wherein the compound has the formula (V): where R 1 is hydrogen, alkyl or halo; R 2 is hydrogen or alkyl; R 3 is chloro, methyl, amino, carboxy, ethylaminocarbonyl, isopropylaminocarbonyl, cyclopropylaminocarbonyl, benzylaminocarbonyl, morpholinocarbonyl, aminocarbonyl, methoxycarbonyl, ethoxycarbonyl, ethoxycarbonylamino, isopropyloxycarbonylamino, isobutyloxycarbonylamino, phenylaminocarbonyl, oxazolyl, triazinyl or ethylaminocarbonylamino; R 4 is selected from the group consisting of hydrogen, halo, alkyl, alkoxy and hydroxy; R 6 is selected from the group consisting of hydrogen, halo, alkyl and alkoxy; and Q 1 is alkyl, alkoxy, aralkylamino, alkylamino or cycloalkylamino; wherein “alkyl” means a straight- or branched-chain unsubstituted hydrocarbon group of 1-to-20 carbon atoms; “alkoxy” means a radical —OR, where R is alkyl, as defined above; “halo” means fluoro, chloro, bromo or iodo; “cycloalkyl” means a saturated or partially-unsaturated nonaromatic cyclic hydrocarbon ring system containing 1-to-3 rings with 3-to-7 carbons per ring, which may be further fused with an unsaturated C 3 -C 7 -carbocyclic ring; and “aryl” means a monovalent monocyclic or bicyclic aromatic hydrocarbon radical of 6-to-10 ring atoms, where the aryl ring may optionally be fused to a 5-, 6- or 7-membered monocyclic saturated ring optionally containing 1 or 2 heteroatoms independently selected from oxygen, nitrogen and sulfur, with the remaining ring atoms being carbons, wherein one or two carbon atoms may be optionally replaced by a carbonyl group.
