PROCESS FOR THE PREPARATION OF 4-METHYL-BIPHENYL DERIVATIVES |
| abstract |
The subject of the invention is a process for the preparation of 4-methyl-biphenyl derivatives of general formula: (CF DRAWING IN BOPI) in which R represents a cyano or protected tetrazolyl group of formula: (CF DRAWING IN BOPI) in which R1 located in position 1 or 2 of the tetrazolyl group represents a protective group, characterized in that a halobenzene of formula is reacted: (CF DRAWING IN BOPI) in which Hal represents a halogen atom and R has the same meaning as previously, with a p-tolymagnesium halide in the presence of a polyether, linear or branched, and of a catalyst containing a transition metal. |
