Electric Literature of 77317-55-6,Some common heterocyclic compound, 77317-55-6, name is Methyl 2-amino-5-iodobenzoate, molecular formula is C8H8INO2, 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.
To a solution of 4-fluorobenzyl zinc chloride (0.5M solution in THF, 27.ImL, 13.55mmol) was added PdCl2(dppf)CH2Cl2 (221mg, 0.27mmoL) and the solution was stirred for 5 minutes. To the solution was added 5-iodoanthranilic acid methyl ester (1.5g, 5.4mmol) and the solution was heated to 70 0C for 1 hour. Allowed to cool, quenched with saturated NH4CI, followed by saturated aqueous Na2EDTA, the solution was extracted with CH2CI2, dried (MgSO4), filtered, and concentrated to yield compound 102 A (1.4g, 100%)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Methyl 2-amino-5-iodobenzoate, its application will become more common.
