Synthetic Route of 13421-00-6, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 13421-00-6 as follows.
EXAMPLE 64a Preparation of intermediate 5-chloro-2-Iodo-benzaldehyde To a solution of 5-chloro-2-iodo benzoic acid (4.92 g, 17 mmol) (TRANS) in anhydrous tetrahydrofuran (100 mL) at 0 C. was added borane tetrahydrofuran (1 M, 34 mL, 34 mmol) dropwise. The reaction mixture was then stirred at room temperature for 18 h. The mixture was concentrated and residue was partitioned between ethyl acetate and water. Organic layer was separated, washed with brine, dried over MgSO4, and concentrated to give a colorless oil. The oil was dissolved into 1,2-dichloroethane (50 mL), and activated MnO2 (15 g) was added. The mixture was then heated at reflux for 2 h, cooled to room temperature, and filtered through a short pad of celite. The filtrated was concentrated and purified by chromatography (EtOAc:hexanes=1;8) to give 5-chloro-2-Iodo-benzaldehyde as a white solid (Yield 5.5 g, 25%).
According to the analysis of related databases, 13421-00-6, the application of this compound in the production field has become more and more popular.
