Abstract
Procedure for the preparation of new biphenyl derivatives of the general formula I, **(See formula)** wherein the radical signifies a halogen atom and the radical B signifies the hydroxy group, an alkoxy or aralkoxy group or a group of the formula (see formula), in which R3, and R4, which may be the same or different from each other, represent hydrogen atoms, the carboxymethyl radical, a lower alcohol radical or a phenyl radical optionally substituted by a hydroxy or methyl group, and, if that B means the hydroxy group, of its salts with organic or inorganic bases, characterized in that for the preparation of compounds of the general formula I, in which the radical B represents the hydroxy group, biphenyl-butyronitriles of the formula are saponified general II **(See formula)** in which the radical has the meanings indicated above, in the presence of a base or an acid at temperatures between 100º and 200ºC or, for the preparation of the same compounds of the general formula I, butyronitriles of the general formula are saponified and decarboxylated IIa **(See formula)** wherein the radical R1 represents a halogen atom and the radical means the cyano or carboxamido group or a carboxyl group, which may optionally be esterified with an aliphatic or araliphatic alcohol or with a phenol: o Nitriles are reduced, saponified and decarboxylated the general formula IId **(See formula)** wherein the radicals R1 and Q are as defined above or, for the preparation of compounds of the general formula I, in which B means the free amino group, a nitrile of the general formula II is partially saponified; and the eventually obtained racemates are split by fractional crystallization of their salts with optically active bases into their two optically active individual components, and if desired, compounds obtained from the general formula I, in which B means the alkoxy group, or are saponified to form compounds of the general formula I, in which B represents the hydroxy group, and if desired, compounds obtained from the general formula I, in which B is the hydroxy group, are transformed according to methods customary in their esters or in its salts by means of organic or inorganic bases or, if desired, for the preparation of compounds of the general formula I, in which B means the radical (see formula) A compound of the general formula I, in which B represents an alkoxy group or a halogen atom, is reacted with a primary or secondary amine at elevated temperatures.
