Method for preparing 4-methyl-biphenyl derivatives |
| abstract |
The subject-matter of the invention is a process for the preparation of substituted 4-methylbiphenyls of general formula:in which R is a cyano group or a protected tetrazolyl group of formula:in which R1, situated at the 1 or 2 position of the tetrazolyl group, is a protective group, characterized in that a halobenzene of formula:in which Hal is a halogen atom and R has the same meaning as above, is reacted with a p-tolylmagnesium halide in the presence of a linear or branched polyether and of a catalyst comprising a transition metal. |
