| titleOfInvention | Trisubstituted biphenyls and a method for producing trisubstituted biphenyls |
| abstract | CLAIMS 1. Trisubstituted biphenyls of general formula I in which R1ndenotes a carboxylic acid or a C1-C6-alkoxycarbonyl,nR2 is an unbranched or branched groupnC1-C6-alkyl, R3 represents a chlorine and bromine fluorine groupnhydroxy, cyano, C1-C6-alkoxy, unbranched ornbranched C1-C6-alkyl, trifluoromethyl, trifluoromethoxy, carboxamide, carboxyl, C1-C6-alkoxycarbonylnor nitro and R4 is a tetrazolyl moiety, andntheir salts.nPL 17βΤ7-Β B1n5. A method for producing trisubstituted biphenyls of formulanIs a carboxy residue or a Ci-C6alkoxycarbonyl residue,nr2 is unbranched or branchedna C1-C6-alkyl group, R3 represents a fluorine, chlorine, bromine atom,nhydroxy, cyano, C1-C6-alkoxy, unbranchednor branched C 1 -C 6 alkyl group, trifluoromethyl group,ntrifluoromethoxy, carboxamide, carboxylic acid,nCi-C6-alkoxycarbonyl or nitro and R4 is the moiety orna tetrazolyl, characterized in that (1) a pyridone of the general formula 2,nin which R © r2 are as defined above, is reacted,nin an inert solvent in the presence of a base and optionally withnby addition of a catalyst, with the general compound of formula 3, wnwhere r3 is as defined above, R4 represents the remainder of the formulan8 and E is chlorine or bromine, then obtainednthe product cleaves the protective triphenylmethyl group into the knownnthe method, and then the compound obtained is optionally carried outnin salt. |
