Related Products of 10488-69-4 , The common heterocyclic compound, 10488-69-4, name is Ethyl 4-chloro-3-hydroxybutanoate, molecular formula is C6H11ClO3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Example 1; [60] 61.5 g (1.626 mol) of sodium borohydride was dissolved in 694 mL of toluene, and52 g (1.626 mol) of methanol was added drop wise at room temperature for 1 hour. Subsequently, 300 g (1.807 mol, 99.3percent ee) of ethyl (S)-4-chloro-3-hydroxybutyrate was added, and stirring was performed at room temperature for 12 hours. The reaction mixture was cooled below 100C and, after adding 183 g of 36percent HCl dropwise, the solvent was removed by distillation under reduced pressure below 400C. Using 800 mL of methanol, concentration under reduced pressure was performed for 3 times below 40 C. 800 mL of dichloromethane was added to the resultant residue. After filtering off
The synthetic route of 10488-69-4 has been constantly updated, and we look forward to future research findings.
