These common heterocyclic compound, 1094759-93-9, name is 4-Chloro-5-fluoro-2-iodoaniline, its 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. Application In Synthesis of 4-Chloro-5-fluoro-2-iodoaniline
To Intermediate 5A (47g, 17.3 mmol) in AcOH (470 mL) was added NaN3 (33.76g, 51.9 mmol) and trimethyl orthoformate (56.8 mL, 51.9 mmol). After 30 h, the reaction was poured into ice H2O, the solids were filtered-off and washed with petroleum ether to afford 49 g Intermediate 5B. MS (ESI) m/z: 324.8 (M+H)+.
The synthetic route of 4-Chloro-5-fluoro-2-iodoaniline has been constantly updated, and we look forward to future research findings.
