Synthetic Route of 1829-28-3,Some common heterocyclic compound, 1829-28-3, name is Ethyl 2-iodobenzoate, molecular formula is C9H9IO2, 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.
Weighing 5.52 g (20 mmol) of o-iodobenzoic acid ethyl ester obtained by esterification of o-iodobenzoic acid with anhydrous ethanol in a microwave reaction tube, 1.08 g (10 mmol) of o-phenylenediamine.Add copper iodide (190 mg, 1 mmol) in turn,Potassium phosphate (6.36g, 30mmol),Appropriate amount of ethylene glycol and magnetron at 180 C,Microwave reaction under nitrogen protection,The reaction was stopped after 1 h, and the reaction was terminated by TLC. Extraction with ethyl acetate (3 x 100 mL),Wash with water and an appropriate amount of saturated brine, combine the organic layers, add anhydrous Na2SO4 to remove water,After filtration, the residue was concentrated and the residue was purified by column chromatography to yield 1.The yield of the obtained Compound 1 was 65%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Ethyl 2-iodobenzoate, its application will become more common.
