2, 3, and 4 (α,α,β,β Tetrafluorophenethyl)benzylamines. A new class of antiarrhythmic agents

Upon finding 2-(α,α,β,β-tetrafluorophenethyl)benzylamine (4) to be a potent and novel type of antiarrhythmic agent, 2-, 3-, and 4-(α,α,β,β-Tetrafluorophenethyl) benzylamines were synthesized. Structure-activity relationships in this series are described.

Tetrafluorophenethylaralkylamine compounds

New fluoro derivatives of aralkylamine compounds, particularly 2-(2-phenyl-1,1,2,2-tetrafluoroethyl)benzylamine, as well as the N-alkyl and the N,N-dialkyl derivatives thereof are prepared by reaction of 2-bromobenzonitrile with benzylmagnesium chloride to produce 2'-bromo-2-phenylacetophenone; oxidation of said acetophenone with selenous acid to produce 2-bromobenzil; conversion of the benzil compound by treatment with sulfur tetrafluoride to the corresponding 2-bromo-α ,α-α',α'-tetrafluorobibenzyl; followed by reaction of the 2-bromobibenzyl compound with a metal cyanide to produce the corresponding 2-(2-phenyl-1,1,2,2-tetrafluoroethyl)benzonitrile. This nitrile compound is then reduced with lithium aluminum hydride to produce the corresponding benzylamine, which is then converted, if desired, to the N-alkyl and/or N,N-dialkyl 2-(2-phenyl-1,1,2,2-tetrafluoroethyl)benzylamine. Alternatively, the nitrile or the precursor bromobibenzyl can be converted by Grignard reactions to the corresponding α-alkyl or α,α-dialkylbenzylamine which can then be converted if desired to the corresponding N-alkyl and/or N,N-dialkyl substituted benzylamine compound. The phenyltetrafluoroethylbenzylamine as well as its N-alkyl and N,N-dialkyl derivatives are active as antiarrhythmic agents.
