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. 5471-81-8, name is Methyl 4-iodo-3-methylbenzoate, A new synthetic method of this compound is introduced below., category: iodides-buliding-blocks
Methyl 4-formyl-3-methylbenzoate (1616-18a). To a solution of methyl 4-iodo-3- methylbenzoate (1.0 g, 3.6 mmol) in THF (24 mL, 0.15 M) at -15C was added isopropylmagnesium chloride (7.2 ml, 14.5 mmol, 4.0 equiv). The reaction mixture was allowed to continue stirring at -15C for 2 hrs before N,N-dimethylformamide (1.4 ml, 18mmol, 5.0 equiv) was added. The mixture was warmed to room temperature over a period of 1 hr. At this time the reaction was quenched with HC1 and extracted with EtOAc (3x). The combined organic layers were washed with brine and dried over MgSO4, filtered and concentrated in vacuo.Purification was achieved using flash column chromatography on Si02 (Hexanes/EtOAc:6/1) to yield a white solid (0.45 g, 70 %) which was taken on without further purification.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
