Abstract

Dehalogenation of halo-arylalkylamines comprises treating enantiomers of formula (I) with hydrogenation agent in the presence of a transition metal-contg. hydrogenation catalyst to form enantiomers of formula (II) with retention of the active centre. the asterisk indicates the asymmetric centre, m = 1-3; n = 0-4; R1 and R2 = H, 1-10C alkyl, aryl or together complete a 3-8 membered ring; R3, R4 = H, 1-10C alkyl, aryl or together with N complete a 3-8 membered ring, or with R1 or R2 complete a 3-8 membered ring; X = Cl, I or Br.
