Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2905-69-3, name is Methyl 2,5-dichlorobenzoate, A new synthetic method of this compound is introduced below., Recommanded Product: 2905-69-3
EXAMPLE 2 Dehalogenation of Methyl 2,5-Dichlorobenzoate A 50-mL round-bottom flask was equipped with a magnetic stir bar, reflux condenser, thermometer, nitrogen inlet, and heating mantle attached to a temperature controller. The flask was charged with methyl 2,5-dichlorobenzoate (5.0 g, 24 mmol) and copper powder (3.04 g, 48 mmol). Propionic acid (10 mL) and xylenes (15 mL) were added, and the resulting mixture was heated to 130-135 C. The reaction was monitored by GC analysis and was judged to be complete when the starting material was no longer detectable (3 hours). The reaction mixture was cooled to room temperature and filtered; the solids were washed with xylenes. The filtrates were blue-green. The filtrates were combined and washed with 1M hydrochloric acid solution until the blue-green color disappeared. The resulting yellow organic layer was washed with water and dried over sodium sulfate. The solvent was removed by evaporation under reduced pressure. The residue was dried under vacuum, yielding 3.93 g of methyl 3-chlorobenzoate as a pale yellow oil.
The synthetic route of 2905-69-3 has been constantly updated, and we look forward to future research findings.
