    摘要: A process for obtaining 2′-halo-4-methylbiphenyls is described, which comprises reacting 4 halotoluene with a 1,2-dihalobenzene in the presence of elemental metal such as magnesium, lithium or zinc, wherein 0 to 0.9 molar, particularly 0 to 0.2 molar excess of 4-halotoluene in regard to 1,2-dihalobenzene is used, and arised organometal intermediates are quenched by elemental mental halogen. In addition, the coupling of arised 2′-halo-4-methylbiphenyls with 2-(1-propyl)-4-methyl-6-(1′-methylbenzimidazole-2-il)benzimidazole to afford 3′-(2′-halo-biphenyl-4-ylmethyl)-1,7′-dimethyl-2′-propyl-1H,3′H-[2,5′]bibenzoimidazolyl, which can be further converted to organometallic compound and said organometallic compound is further reacted with formic acid derivative, such as N,N-dimethylformamide, alkylformiate or carbon dioxide to obtain telmisartan, is also described. Further described is use of in line analytics for monitoring the aforementioned reactions, process for preparing a pharmaceutical composition and/or dosage for, or use in preparing a medicament.
