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.
