Synthetic Route of 19094-56-5, These common heterocyclic compound, 19094-56-5, name is 2-Chloro-5-iodobenzoic acid, 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.
To a dried flask, 5-iodo-2-chlorobenzoic acid (20.0 g, 70.8 mmol) and dichloromethane (60 mL) were added. The reaction mixture was stirred, then oxalyl chloride (9.8 g, 77.9 mmol) and DMF (0.2 mL) were slowly added dropwise, and some bubbles were observed. The reaction mixture was stirred at room temperature for 7 hours. The solvent and excess oxalyl chloride were removed by rotary evaporation to give a gray solid, which was used directly in the next step without further purification.
The synthetic route of 19094-56-5 has been constantly updated, and we look forward to future research findings.
