Claims
exact text as granted — not AI-modified1 .- 20 . (canceled)
21 . A process for preparing (S)-(+)-N-methyl-[3-(1-naphthyloxy)-3-(2-thienyl)-propyl]-amine comprising converting a compound of formula I
to (S)-(+)-N-methyl-[3-(1-naphthyloxy)-3-(2-thienyl)-propyl]-amine, wherein R 1 is thienyl and R 2 is methyl.
22 . The process of claim 21 , wherein the compound of formula I is (S)— (−)-3-N-methylamino-1-(2-thienyl)-1-propanol.
23 . A compound of formula I
and/or an additional salt of a proton acid, wherein R 1 and R 2 independently represent alkyl, cycloalkyl, aryl or aralkyl, each aryl or aralkyl being optionally further substituted with alkyl, alkoxy and/or halogen.
24 . The compound of claim 23 , wherein R 1 is thienyl and R 2 is methyl.Join the waitlist — get patent alerts
