Adding a certain compound to certain chemical reactions, such as: 6188-23-4, 6-Bromoimidazo[1,2-a]pyridine, 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, Recommanded Product: 6188-23-4, blongs to pyridine-derivatives compound. Recommanded Product: 6188-23-4
A mixture of the compound of example 1 (1.0 g, 5.08 mmol) and t-butyl 4-(5-(4, 4,5,5- tetramethyl-1 ,3,2-dioxaborolan-2-yl)pyridin-2-yl)piperazine-1-carboxylate (1.97 g, 5.08 mmol) were treated with [1 ,1 ‘-bis(diphenylphosphino)-ferrocene]dichloropalladium(ll) complex with dichloromethane (0.124 g, 0.152 mmol) and sodium carbonate (2.15 g, 20.30 mmol) in dry dimethylformamide (100 mL) according to the procedure for the preparation of the compound of example 2 to afford the title compound. Yield: 1.05 g (54.68 %); 1H NMR (DMSO-d6, 300 MHz): delta 1.39 (s, 9H, 3CH3), 3.44 (s, 4H, 2CH2), 3.55 (s, 4H, 2CH2), 6.95 (d, 1H, J=8.7 Hz, Ar), 7.50-7.62 (m, 3H, Ar), 7.87 (d, 1H, J=2.4 Hz, Ar), 7.90 (s, 1H, Ar), 8.46 (d, 1H, J=2.4 Hz, Ar), 8.83 (s, 1H, Ar); MS (ES+): m/e 380 (M+1).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,6188-23-4, 6-Bromoimidazo[1,2-a]pyridine, and friends who are interested can also refer to it.
