or a salt or purified stereoisomer thereof,
with the proviso that at least one of X 1 to X 7 is OH or —OC(O)C 1 -C 4 alkyl.
2. A compound of claim 1 wherein X 1 is OH or —OC(O)C 1 -C 4 alkyl.
3. A compound of claim 1 wherein X 2 is OH or —OC(O)C 1 -C 4 alkyl.
4. A compound of claim 1 wherein X 3 is OH or —OC(O)C 1 -C 4 alkyl.
5. A compound of claim 1 wherein X 4 is OH or —OC(O)C 1 -C 4 alkyl.
6. A compound of claim 1 wherein X 5 is OH or —OC(O)C 1 -C 4 alkyl.
7. A compound of claim 1 wherein X 6 is OH or —OC(O)C 1 -C 4 alkyl.
8. A compound of claim 1 wherein X 7 is OH or —OC(O)C 1 -C 4 alkyl.
9. A compound of claim 1 wherein Hal is chlorine.
10. A compound of claim 1 which is 4-{4-[({[4-chloro-3-(trifluoromethyl) phenyl]amino}carbonyl)amino]2-(hydroxy)phenoxy}-2-pyridine carboxamide.
11. A compound of claim 1 which is 4-{4-[({[4-chloro-3-(trifluoromethyl)phenyl]amino}carbonyl)amino]3-(hydroxy)phenoxy}-2-pyridine carboxamide.
12. A compound of claim 1 which is 4-{4-[({[4-chloro-3-(trifluoromethyl) phenyl]amino}carbonyl)amino]5-(hydroxy)phenoxy}-2-pyridine carboxamide.
13. A compound of claim 1 which is 4-{4-[({[4-chloro-3-(trifluoromethyl) phenyl]amino}carbonyl)amino]6-(hydroxy)phenoxy}-2-pyridine carboxamide.
