Adding a certain compound to certain chemical reactions, such as: 1643-29-4, name is 3-(4-Iodophenyl)propanoic acid, belongs to iodides-buliding-blocks 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 1643-29-4, Formula: C9H9IO2
General procedure: The reaction is carried out under an argon atmosphere. A mixture of 3-(4-bromo- phenyl)-propionic acid (500 mg; 2.18 mmol) and 1 ,T-carbonyldiimidazole (389 mg; 2.40 mmol) in 10 mL dichloromethane is stirred at room temperature for 1 hour. Triethylamine (440 pl3.27 mmol) and N,O-dimethylhydroxylamine hydrochloride (234 mg; 2.40 mmol) are added. After stirring at room temperature for 18 hours the organic layer is washed with HCI (1 M aqueous solution), water and NaHCOs (saturated aqueous solution). The organic layer is dried and concentrated under reduced pressure. The residue is further used as crude product.Yield: 560 mg (94% of theory) HPLC (Method 2): Retention time = 1.026 min.
