Patent ID: 7947721

Claim:
A compound of formula A wherein: Q is selected from the group consisting of a salt of COOH, CONR′R″, SO 3 H or a salt thereof, and SO 2 NR′R″; P is selected from the group consisting of (a), (b), (c) and (d) R 1 is selected from the group consisting of Cl, Br, I, CH 3 , CF 3 , CHF 2 , and CH 2 F; R 3 is H or CH 3 ; R′ and R″ are independently selected from the group consisting of H, lower alkyl, and lower alkyl substituted with one or more OR, CO 2 R, NHR, NR 2 , or CF 3 groups wherein R is H or lower alkyl, or R′ and R″ together with the nitrogen atom to which they are attached form a 4-, 5-, or 6-membered heterocyclic ring; R O is selected from the group consisting of Cl, Br, CF 3 and methyl; R P is selected from the group consisting of halogen, methyl, ethyl, propyl, isopropyl, cyclopropylmethyl, and C 3 -C 6 eyeloalkyl; R 4 , R 5 and R 6 are independently selected from the group consisting of H, F, Cl, Br, CH 3 , CF 3 , CFH 2 , CF 2 H, isopropyl, cyclopropyl, OCH 3 , OH, OCF 3 , NH 2 and NHCH 3 ; U and U′ are independently selected from N and CH; R 7 is selected from the group consisting of Cl, Br, I, CH 3 , CF 3 , OCH 3 , isopropyl, cyclopropyl, tert-butyl, and cyclohutyl; and R 8 , R 9 , R 10 and R 11 are independently H or CH 3 ; with the provisos that, when Q is SO 2 NH 2 , R 1 is not methyl unless R P is halogen, cyclopropylmethyl or C 3 -C 6 cycloalkyl, and R 7 is methyl only if R 6 is methyl.
