Patent ID: 7790758

Claim:
A compound of formula (I), or a salt thereof wherein R 1 is selected from C 1-6 alkyl, haloC 1-6 alkyl, C 2-6 alkenyl, amino, monoC 1-4 alkylamino and diC 1-4 alkylamino; R 2 , R 3 and R 6 , which may be the same or different, are each independently selected from hydrogen, halogen, C 1-6 alkyl, haloC 1-6 alkyl and C 1-4 alkoxy; each R 4 , which may be the same or different, is selected from C 1-6 alkyl, halogen, haloC 1-6 alkyl, C 1-4 alkoxy, haloC 1-4 alkoxy and cyano; p is selected from 0, 1 and 2; and R 5 is phenyl or an aromatic heterocyclyl, either of which is optionally substituted with one or more groups Y; each Y group is independently selected from the group consisting of: C 1-6 alkyl, halogen, haloC 1-6 alkyl, C 1-4 alkoxy, haloC 1-4 alkoxy, cyano, —(CH 2 ) q NR 5a SO 2 R 5b , —(CH 2 ) q NR 5a (C═O)R 5d , —(CH 2 ) q NR 5a (C═O)N(R 5c ) 2 , —(CH 2 ) q (C═O)R 5d , —(CH 2 ) q SO 2 R 5b ; where R 5a and each R 5c , which may be the same or different, is selected from hydrogen and C 1-6 alkyl; R 5b is selected from C 1-6 alkyl and haloC 1-6 alkyl; R 5d is selected from C 1-6 alkyl, C 1-4 alkoxy and haloC 1-6 alkyl; or R 5a and R 5b , R 5a and R 5c , or R 5a and R 5d , where appropriate, together with the interconnecting atoms, may form a 5- or 6-membered ring; and q is 0, 1, or 2; in the case when there are two or more Y groups present, two of them together may form a cyclic group selected from —(CH 2 ) r OR 5e O(CH 2 ) s — and —(CH 2 ) t OR 5e — where R 5e is a group selected from C 1-4 alkylene or halo C 1-4 alkylene; r and s are each independently 0, 1 or 2; and t is 2 or 3.
