Introduction of a new synthetic route about 139481-72-4

The synthetic route of 139481-72-4 has been constantly updated, and we look forward to future research findings.

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. 139481-72-4, name is Trityl candesartan belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. 139481-72-4

Potassium carbonate (60 gm), 1-chloroethylcyclohexyl carbonate (60 gm) and potassium iodide (20 gm) were added to the solution of 2-Ethoxy-1-[[2′-(N- triphenylmethyltetrazole-5-yl)biphenyl)-4-yl]methyl]benzimidazole-7-carboxylic acid (100 gm) in dimethylformamide (500 ml) at room temperature. Raised the temperature to 750C, stirred for 2 hours, cooled to room temperature and 5% sodium chloride solution (2000 ml) was added. Maintained for 15 minutes, ethyl acetate (400 ml) was added, stirred and separated the layers. Aqueous layer was extracted with ethyl acetate (400 ml), organic layer was taken, washed with 10% sodium chloride solution (400 ml), concentrated, and co-distilled with ethyl acetate (100 ml). Mixture of ethyl acetate (500 ml) and n-hexane (500 ml) were added to the residual mass, stirred for 6 hours at room temperature, cooled to 50C, stirred for 1 hour, filtered, then washed with mixture of ethyl acetate (50 ml) and n-hexane (200 ml) and dried for 6 hours to obtain 1-(Cyclohexyloxy carbonyloxy)ethyl-2-ethoxy-1-[[2′-(1H-tetrazole-5-yl)biphenyl-4-yl]methyl] benzimidazole-7-carboxylate (110 gm, HPLC Purity: 99%).

The synthetic route of 139481-72-4 has been constantly updated, and we look forward to future research findings.
