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. 162848-16-0, name is 4-[1,2,4]Triazol-1-yl-benzoic acid, A new synthetic method of this compound is introduced below., Recommanded Product: 4-[1,2,4]Triazol-1-yl-benzoic acid
To a solution of the amine (157 mg, 0.66 mmol), 4-(1H-1,2,4-triazol-1-yl)benzoic acid (132 mg, 0.69 mmol), EDCI hydrochloride (145 mg, 0.76 mmol), HOBT (106 mg, 0.78 mmol) in 6.0 mL of DMF was added N-methylmorpholine (0.15 mL, 1.36 mmol) and stirred at ambient temperature for 24 h. The reaction mixture was partitioned between 50 mL of water and 50 mL of ethyl acetate. The organic layer was washed with two 50 mL portions of 1N HCl solution, 50 mL of water, dried over sodium sulfate, filtered, concentrated and purified by column chromatography (methanol/methylene chloride, 3:97) to give 170 mg of N-[(1S,2R)-2-({[(1S)-1-cyano-3-methylbutyl]amino}carbonyl)cyclohexyl]-4-(1H-1,2,4-triazol-1-yl)benzamide as a white solid. Yield: 63%, MS: 409 (M+H+), mp=156.0-158.9 C.
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.
