Adding a certain compound to certain chemical reactions, such as: 312-73-2, name is 2-(Trifluoromethyl)-1H-benzo[d]imidazole, belongs to imidazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 312-73-2, Formula: C8H5F3N2

General procedure: mixtureof benzimidazole derivative (0.01 mol, insoluble in H2O) and correspondingacid (0.01 mol, insoluble in H2O) in absolute methanol (25 ml)was stirred at 65 C for 1-3 h. The solvent was distilled off, and theresidue was multiply washed with diethyl ether and dried (24 h) overP2O5 at ~0.01 Torr to afford viscous liquids or powders (soluble in water).Compounds 14, 15 were prepared by the reaction of ion exchange undersimilar conditions for 7-8 h.

G. Synthesis of Compounds 46 and 47A stirred mixture of 2-Trifluoromethyl-I H-benzoimidazole (4.92g, 26.4 mmol), 4-fluorobenaldehyde (3.1 mL, 29.1 mmol), and K2CO3 (4.37g, 31.7 mmol) in DMF (50 mL) was heated to 150 0C for 16 h. After being cooled to room temperature, the reaction mixture was partitioned between H2O and EtOAC. After usual workup, the crude product was purified by silica gel chromatography (20% Hexane/EtOAc to 30% Hexane/EtOAc) to afford a yellow oil which was subjected to a second silica gel chromatography (DMC) to provide the aldehyde intermediate 4-(2-Trifluoromethyl-benzoimidazol-1-yl)- benzaldehyde as a white solid (4.0 g).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(Trifluoromethyl)-1H-benzo[d]imidazole, its application will become more common.

Here is a downstream synthesis route of the compound 312-73-2. 312-73-2

General procedure: A solution of this chloromethyl ester (1.8 mmol) in N,N-dimethylformamide (4 ml) was treated with the 2-substituted benzimidazoles (1.8 mmol) and cesium carbonate (2.8 mmol). The mixture was stirred for 3 h at r.t. and partitioned with water and ethyl acetate (20 ml). The aqueous layer was further extracted with ethyl acetate (20 ml) and the combined organic layers washed with brine (20 ml), dried (sodium sulfate), filtered and concentrated. Flash chromatography with ethyl acetate provided the desired product as colored oil.
