Adding a certain compound to certain chemical reactions, such as: 188577-68-6, 4,5-Dichloropyridin-2-amine, 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, Product Details of 188577-68-6, blongs to pyridine-derivatives compound. Product Details of 188577-68-6
Example 188 Synthesis of 6,7-dichloro-2-(chloromethyl)imidazo[1,2-a]pyridine. The mixture of 4,5-dichloropyridin-2-amine (1 g, 6.13 mmol) and 1,3-dichloropropan-2-one(10 g, 78.4 mmol) in DMF (20 mL) was stirred at 90 C. for 20 h. Then H2O (100 mL) was added and extracted with EtOAc (100 mL*2). The combined organic layers were concentrated to give the crude product which was purified by silica gel chromatography (PE/EtOAc=3/1) to give 6,7-dichloro-2-(chloromethyl)imidazo[1,2-a]pyridine (471 mg, yield: 33%) as a yellow solid. ESI-MS [M+H]+: 235.1
The synthetic route of 188577-68-6 has been constantly updated, and we look forward to future research findings.
