Patent ID: 7078537

Claim:
A racemic or enantiomerically enriched phenylalkyldiamine compound represented by the structural formula (I): wherein m is 1, n is 1, X and Y are independently selected from the group consisting of hydrogen, lower alkyl of 1 to 8 carbon atoms, halogen selected from F, Cl, Br and I, alkoxy containing 1 to 3 carbon atoms, nitro, hydroxy and trifluoromethyl; R 1 and R 2 are hydrogen, and Z is a radical derived from 5 to 7-membered aliphatic cyclic compounds selected from hexamethyleneimine, 4-benzylpiperidine, N-benzylpiperazine, substituted 4-benzoylpiperidine and their derivatives having the general formula (II) or (II′) wherein X′ and Y′ are independently selected from the group consisting of hydrogen, lower alkyl of 1 to 8 carbon atoms, halogen selected from F, Cl, Br and I, alkoxy containing 1 to 3 carbon atoms, nitro, hydroxy, and trifluoromethyl; and the pharmaceutically acceptable salts thereof.
