TREATMENT OF CNS DISORDERS WITH trans 4-(3,4-DICHLOROPHENYL)-1,2,3,4-TETRAHYDRO-1-NAPHTHALENAMINE

Abstract

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.

1 . A method for treating speech disorders, the method comprising administering to a patient in need of treatment 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.
