Tert-Butyl 4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl]piperidine-1-carboxylate is a specialized boronic ester intermediate widely utilized in cross-coupling reactions. Its molecular formula is C18H27N3O4B, and the CAS registry number is 1096623-34-7. The compound is typically synthesized via palladium-catalyzed coupling of tert-butyl 4-bromopiperidine-1-carboxylate with pyrazole derivatives followed by borylation.
Store under inert atmosphere at low temperatures to prevent hydrolysis. Handle with appropriate PPE as it may cause skin irritation; ensure proper ventilation during processing.
