Adding a certain compound to certain chemical reactions, such as: 19718-49-1, name is Methyl 4-amino-3-iodobenzoate, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 19718-49-1, HPLC of Formula: C8H8INO2
General procedure: A solution of 2-iodoaniline (333.6 mg, 1.52 mmol, 1.0 equiv) in DCM (5.0 mL) was added with Et3N (0.23 mL, 166.9 mg, 1.65 mmol, 1.1 equiv). The reaction solution was cooled at 0 C and acetyl chloride (0.28 mL, 308 mg, 3.92 mmol, 2.6 equiv) was added into the cooled solution. The resulting mixture was warmed to stir at room temperature overnight. Upon completion, thereaction was added with water and the separated aqueous phase was extracted with EtOAc (3xtimes). The combined organic phases were washed with sat. aq. NaCl, dried over anh. Na2SO4 and concentrated under reduced pressure. The crude material was purified by SiO2 column chromatography eluting with 30% EtOAc-hexane to yield 387.9 mg (98%) of the corresponding N-(2-iodophenyl)acetamide as a white solid.
