Claims (71)

1. A method for the treatment of a disorder selected from migraine, dystonia, depression, anxiety, or amyotrophic lateral sclerosis (ALS) comprising administering an effective amount of a compound of formula 2 or a pharmaceutically acceptable salt thereof to a subject in need thereof:

wherein

R 1 is halogen, optionally substituted C 1 -C 3 alkyl, cyclopropyl, optionally substituted C 1 -C 3 alkoxy, cyano, hydroxyl, nitro or NH 2 ;

R 2 is H or F; and

Q is an optionally substituted pyridyl or pyrazyl group.

2. The method according to claim 1 , wherein the disorder is migraine.

3. The method according to claim 1 , wherein the disorder is dystonia.

4. The method according to claim 1 , wherein the disorder is depression.

5. The method according to claim 1 , wherein the disorder is anxiety.

6. The method according to claim 1 , wherein the disorder is amyotrophic lateral sclerosis (ALS).

7. The method according to claim 4 , wherein the depression is treatment-resistant depression.

8. The method according to claim 1 , wherein the compound is a compound of formula 3:

or a pharmaceutically acceptable salt thereof, wherein

R 1 is halogen, optionally substituted C 1 -C 3 alkyl, cyclopropyl, optionally substituted C 1 -C 3 alkoxy, cyano, hydroxyl, nitro or NH 2 ;

R 2 is H or F;

R 3 is H, halogen, optionally substituted C 1 -C 3 alkyl, optionally substituted C 1 -C 3 alkoxy or cyano; and

R 4 is H, halogen, optionally substituted C 1 -C 3 alkyl, optionally substituted C 1 -C 3 alkoxy or cyano; and

n is 0-3.

9. The method according to claim 1 , wherein the compound is a compound of formula 4:

or a pharmaceutically acceptable salt thereof, wherein

R 1 is halogen, optionally substituted C 1 -C 3 alkyl, cyclopropyl, optionally substituted C 1 -C 3 alkoxy, cyano, hydroxyl, nitro or NH 2 ;

R 2 is H or F; and

R 3 is H, halogen, optionally substituted C 1 -C 3 alkyl, optionally substituted C 1 -C 3 alkoxy or cyano.

10. The method according to claim 1 , wherein the compound is a compound of formula 5:

or a pharmaceutically acceptable salt thereof, wherein

R 1 is halogen, optionally substituted C 1 -C 3 alkyl, cyclopropyl, optionally substituted C 1 -C 3 alkoxy, cyano, hydroxyl, nitro or NH 2 ;

R 2 is H or F;

R 5 is H, D, halogen, optionally substituted C 1 -C 3 alkyl or cyano; and

R 6 is H, D, halogen, optionally substituted C 1 -C 3 alkyl or cyano.

11. The method according to claim 1 , wherein R 1 is F, Cl, OMe, CH 2 OMe, Me, fluoromethyl or cyano.

12. The method according to claim 1 , wherein R 1 is F, Cl or cyano.

13. The method according to claim 8 , wherein R 3 is H, Me, F, Cl or cyano.

14. The method according to claim 8 , wherein n is 0 or 1.

15. The method according to claim 10 , wherein R 5 and R 6 are independently H, D or F.

16. The method according to claim 1 , wherein the compound is selected from the group consisting of:
