These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,153747-97-8, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 153747-97-8, tert-Butyl 4-(5-bromopyridin-2-yl)piperazine-1-carboxylate, 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, 153747-97-8, blongs to pyridine-derivatives compound. Computed Properties of C14H20BrN3O2

General procedure: A reaction tube was charged with benzenesulfonyl fluorideboronic acid 3 (61 mg, 0.30 mmol, 1.5 equiv), Pd(OAc)2 (2.3 mg, 0.010 mmol, 5.0 mol %) and XPhos (9.5 mg, 0.020 mmol, 10 mol %), sealed with a rubber septum, evacuated and back-filled with N2 three times. Degassed 1,4-dioxane (0.8 mL), degassed 1.0 M aq. K3PO4 solution (0.4 mL, 0.40 mmol, 2.0 equiv) and aryl halide* (0.20 mmol, 1.0 equiv) were added subsequently, and the reaction mixture stirred under positive pressure of N2 in a preheated aluminium heating block at 40 C for 4 h (5a, b, f, g, h, l), 6 h (5c, d, e, i, j, m) or 24 h (5k). After cooling to ambient temperature, the reaction mixture was diluted with EtOAc, dried with anhydrous MgSO4, filtered over Celite and concentrated in vacuo. The crude product was purified by flash column chromatography to afford the biarylsulfonyl fluoride. *In the case where aryl halide is a solid, it was added to the vessel before evacuating and back-filling.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,153747-97-8, its application will become more common.
