Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 144689-93-0, name is Ethyl 4-(1-hydroxy-1-methylethyl)-2-propylimidazole-5-carboxylate, A new synthetic method of this compound is introduced below., HPLC of Formula: C12H20N2O3
Example 5; Preparation of ethyl-4-(1-hydroxy-1-methylethyl)-2-propyl-1-{4-[2-(trityl tetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylate4-(1-Hydroxy-1-methylethyl)-2-propyl-1H-imidazole-5-carboxylic acid ethyl ester (100 g), N-(triphenylmethyl)-5-(4′-bromomethyl biphenyl-2-yl)tetrazole (250 g), potassium carbonate (170 g) & tetra butyl ammonium bromide (15 g) in acetone (2.5 L) were refluxed for 10-16 hours. Progress of reaction was monitor by HPLC. After completion of reaction, reaction mass was cooled and filtered to remove the salts. Inorganic salts were washed with acetone (300 mL). Acetone from combine the filtrate and washings was distilled. The residue obtained was crystallized in acetonitrile to get ethyl-4-(1-hydroxy-1-methylethyl)-2-propyl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylate (280 g).HPLC Purity=98.5%
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
