Adding a certain compound to certain chemical reactions, such as: 52548-14-8, name is 2-Iodo-5-methylbenzoic acid, 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 52548-14-8, Formula: C8H7IO2
Step A: H2S04 95-98% (2.54 ml_, 0.048 mol) was added to a solution of 2-iodo-5- methylbenzoic acid (25.0 g, 0.095 mol) in MeOH (220 ml.) and refluxed for 20h. The rxn mixture was cooled with an ice bath, and 1 N aq. NaOH was added dropwise until pH 8 was reached. The org. solvent was removed in vacuo and the aq. layer was extracted with DCM (2x). The combined org. extracts were washed with sat. aq. NaHC03 (1 x) and H20 (1x), dried (Na2S04), filtered and concentrated in vacuo to give methyl 2-iodo-5-methylbenzoate as a pale yellow liquid which was used in the next step without further purification. LC-MS A: tR = 0.87 min; [M+H]+ = 259.22.
