Electric Literature of 61203-48-3,Some common heterocyclic compound, 61203-48-3, name is 2-Iodo-4,5-dimethoxybenzoic acid, molecular formula is C9H9IO4, 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.
General procedure: NaIO4 (6.7 g, 31 mmol, 1.0 equiv) and2-iodobenzoic acid (7.4 g, 30 mmol, 1.0 equiv) were suspended in 30% (v:v) aqueousacetic acid (45 mL). The reaction mixture was vigorously stirred and refluxed for 3 hprotecting from light. Cold water (120 mL) was then added and allowed to cool toroom temperature. After 1 h, the crude product was collected by filtration, washedwith ice water (3 x 30 mL) and acetone (3 x 30 mL). After air-drying in the dark,hydroxybenziodoxole 2 was yielded as a white solid.
The synthetic route of 61203-48-3 has been constantly updated, and we look forward to future research findings.
