Abstract
Official abstract text for this publication.
Treatment of CNS disorders with (1R,4S)-trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine; and (1S,4R)-trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine is disclosed. A process for preparing 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine is also disclosed. The process includes the preparation of all four isomers of N-[4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydronaphthalen-1-yl]formamide, which are also useful.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for treating epilepsy, comprising administering to a patient in need of treatment for epilepsy a therapeutically effective amount of a compound of formula PQ: or a salt thereof. 2. A method according to claim 1 , wherein the compound of formula PQ is selected from formula P and Q: or a salt thereof. 3. A method according to claim 1 , wherein the compound of formula PQ is (1S,4R)—N-[4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine or a salt thereof. 4. A method according to claim 1 , wherein the compound of formula PQ is (1R,4S)—N-[4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine or a salt thereof. 5. A method according to claim 1 , wherein the compound of formula PQ is (1S,4R)—N-[4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine hydrochloride. 6. A method according to claim 1 , wherein the compound of formula PQ is (1R,4S)—N-[4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenamine hydrochloride.
