Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 13526-66-4, name is 3-Bromo-6-chloroimidazo[1,2-b]pyridazine, A new synthetic method of this compound is introduced below., Recommanded Product: 3-Bromo-6-chloroimidazo[1,2-b]pyridazine
To a solution of 3-bromo-6-chloroimidazo[1,2-b]pyridazine (500 mg, 2.15 mmol) in a mixed solvent of dioxane (5 mL) and water (0.5 mL) was added (3-fluorophenyl)boronic acid (273 mg, 1.96 mmol), K2CO3 (811 mg, 5.88 mmol) and Pd(dppf)2Cl2 (79 mg, 0.098 mmol). The reaction mixture was stirred at 80 C. overnight under N2. TLC (PE:EA=5:1) showed the starting material was consumed. The mixture was cooled and concentrated. The residue was purified by column chromatography on silica gel (petroleum ether/EtOAc=20:1 to 1:1) to give 6-chloro-3-(3-fluorophenyl)imidazo[1,2-b]pyridazine (300 mg, 56%) as a yellow solid.
The synthetic route of 13526-66-4 has been constantly updated, and we look forward to future research findings.
