What is the synthesis method of 6-iodo-3,4-dihydroquinoline-2 (1h) -one?
To prepare 6-iodo-3,4-dihydroquinolin-2 (1h) -one, you can follow the following ancient method.
First, take the appropriate raw material and use 2-aminobenzoic acid as the starting material, which is the reaction base. First, 2-aminobenzoic acid and acetic anhydride are co-placed in a reactor, and moderate heat is applied, about 100-120 ° C, to make it acylated. During this process, the amino group of 2-aminobenzoic acid and the acyl group of acetic anhydride undergo nucleophilic substitution to obtain N-acetyl-2-aminobenzoic acid.
Then, an appropriate amount of concentrated sulfuric acid is added to the reaction system, and the temperature is controlled at 150-170 ° C to promote its cyclization. This step is extremely critical. After the nucleophilic substitution in the molecule, the carboxyl group interacts with the acetamide group of the adjacent position to form a quinoline-2-ketone ring system to obtain 3,4-dihydroquinoline-2 (1H) -one.
After the cyclization product is cooled, dissolve it in a suitable organic solvent, such as dichloromethane. Another appropriate amount of iodine is taken, and potassium iodate and sulfuric acid are prepared to form an iodizing agent. Slowly drop the iodizing reagent into the solution containing 3,4-dihydroquinoline-2 (1H) -one and stir at room temperature for a few times. Iodine ions are oxidized by iodate to iodine elemental substance under acidic conditions, and then the 6-position of 3,4-dihydroquinoline-2 (1H) -one is electrophilically substituted to obtain the target product 6-iodo-3,4-dihydroquinolin-2 (1h) -one.
After the reaction is completed, the product is separated and purified from the reaction mixture system by conventional separation and purification methods, such as extraction, column chromatography, etc., and pure 6-iodo-3,4-dihydroquinolin-2 (1h) -one can be obtained.
