Electric Literature of 152628-02-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 152628-02-9, name is 1,7′-Dimethyl-2′-propyl-1H,1’H-2,5′-bibenzo[d]imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
A mixture of I (30.4 g, 0.10 mol), the title compound 4′-chloromethylbiphenyl-2-carbonitrile (0.12 mol) of Example 14, Sodium ethoxide (or other organic bases as described above) (0.3 mol) Mixed with DMF (or other solvents as previously described) (200 ml) and reacted at 65 C for about 5 hours. After TLC was tested for no material, ethylene glycol (100 ml and water (50 ml) (Or other aqueous solvent) and heated to 160 C. TLC detection of no raw materials, the ice water to adjust the concentration of concentrated hydrochloric acid to 5 to 6, The solid was precipitated and the resulting solid was filtered, washed with water, telmisartan crude product, by recrystallization of telmisartan.
The synthetic route of 1,7′-Dimethyl-2′-propyl-1H,1’H-2,5′-bibenzo[d]imidazole has been constantly updated, and we look forward to future research findings.
