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. 152628-02-9, name is 1,7′-Dimethyl-2′-propyl-1H,1’H-2,5′-bibenzo[d]imidazole, A new synthetic method of this compound is introduced below., COA of Formula: C19H20N4
General procedure: To a solution of 1,7′-dimethyl-2′-propyl-1H,3’H-2,5′-bibenzo[d]imidazole 3 (2 mmol) and tetrabutylammonium bromide (0.2 mmol) in benzene (25 mL), a solution of 50% NaOH (25 mL) was added at 0 C followed by the addition of sulfonyl chloride 4 (2.2 mmol). The reaction mixture was stirred vigorously at room temperature for 5-6 h and the reaction was monitored by TLC. After the completion of the reaction, aqueous phase was separated and the organic phase was washed with water (20 mL) and brine (20 mL), dried over anhydrous sodium sulphate and concentrated to give crude products which were purified by column chromatography over silica gel using hexane-EtOAc (6:4) mixture as eluent.
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.
