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. 52099-72-6, name is 1-(Prop-1-en-2-yl)-1H-benzo[d]imidazol-2(3H)-one, A new synthetic method of this compound is introduced below., Recommanded Product: 1-(Prop-1-en-2-yl)-1H-benzo[d]imidazol-2(3H)-one
To a solution of 1-isopropenylbenzimidazolone (500 mg, 2.8 mmol) in dry THF (40 mL) are added triphenylphosphine (902 mg, 3.4 mmol) and (4-Methyl-benzo[>]thiophen-3-yl)-methanol (563 mg, 3.2 mmol). Then diisopropyl azodicarboxylate (0.70 mL, 3.4 mmol) is added drop wise into the above solution after it is cooled down to 0 0C. The mixture is then stirred at room temperature for 5 hr and then the solvent is removed under vacuum and the residue is purified by flash column chromatography using gradient EtOAc/Hexane from 0% to 20% to give 630mg (66%) of 1 -isopropenyl-3-(4-methyl-benzo[£]thiophen-3-ylmethyl)- 1 ,3-dihydro-benzimidazol- 2-one.
The synthetic route of 52099-72-6 has been constantly updated, and we look forward to future research findings.
