90390-33-3, name is 3-Chloro-5-fluorobenzylamine, belongs to chlorides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Application In Synthesis of 3-Chloro-5-fluorobenzylamine
159 mg of 3-chloro-5-fluorobenzylamine (1 mmol) was weighed into a dry 50 mL eggplant-shaped reaction flask, and 15 mL of dichloromethane was added.Stir until the substrate was completely dissolved. After adding 200 muL of triethylamine, a solution of 168 mg of chlorobutyryl chloride (1.2 mmol in a suitable amount of dry dichloromethane) was slowly added dropwise in an ice bath at 0 to 5 C.After the completion of the dropwise addition, the TLC tracking and monitoring were carried out at room temperature, and when the raw materials disappeared, 20 mL of saturated sodium hydrogencarbonate was sequentially used.The water and the saturated aqueous NaCl solution were each washed three times and dried over anhydrous sodium sulfate.The mixture was separated by silica gel column chromatography under reduced pressure to give 4-chloro-N-(3-chloro-5-fluorobenzyl)butanamide.
The synthetic route of 90390-33-3 has been constantly updated, and we look forward to future research findings.
