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., COA of Formula: C10H10N2O
To a solution of l-isopropenyl-2-benzimidazolinone (2 g, 11.5 mmol) in DMF (10 niL) were added ethyl trans-2-hexenoate (2 g, 14 mmol) and the benzyltrimethylammonium hydroxide (40% in MeOH) (0.4 mL, 2.3 mmol) at room temperature. The solution was heated to 60 C for 12 hours. The solution was cooled down and sat.NH4Cl sol was added. The solution was extracted with EtOAc and the combined organic layer was dried with MgSO4 and filtered. The filtrate was concentrated and the residue was purified by CombiFlash with 20% EtOAc in Hexane to afford the desirable product 3-(3-Isopropenyl-2-oxo-2,3-dihydro-benzoimidazol-l- yl)-hexanoic acid ethyl ester (2 g, 55%) as an colorless oil.
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.
