Abstract

Procedure for the preparation of new 4- (4-biphenyl) -4-oxo-butyric acid amides of the general formula I **(See formula)** where it means a hydrogen or halogen atom, the cyano or nitro or amino group, R2 means a hydrogen or halogen atom, R2 and R3, which may be the same or different, mean hydrogen atoms, alcohol radicals with 1 to 5 carbon atoms optionally substituted by a hydroxy or lower alkoxy group, or phenyl radicals which may be substituted by a halogen atom, a trifluoromethyl, hydroxy, lower alcohol or lower alkoxy group, or R3 and R4, together with the atom of nitrogen means a pyrrolidino, piperidino, morpholino or piperazino radical, possibly substituted by a lower alcohol radical, as well as its physiologically compatible salts with organic or inorganic acids, if a compound of the general formula I contains a basic radical, characterized by which a 5- (4-biphenyl) -2 (3H) -furanone of the general formula II is reacted **(See formula)** where and Rg are as initially defined, with an amine of the general formula III **(See formula)** where R3 and R4 are as initially defined; and, in the event that a compound of the general formula I is obtained, which contains a basic radical, this is transformed, if desired, into a physiologically compatible salt with an organic or inorganic acid.
