Used primarily in pharmaceutical research and development as an intermediate in the synthesis of biologically active compounds. Its structure supports the construction of complex molecules through cross-coupling reactions, particularly Suzuki-Miyaura coupling, enabling the formation of carbon-carbon bonds. The presence of the pyrazole ring and the spirocyclic framework makes it valuable in designing kinase inhibitors and other targeted therapies. The tert-butyl carbamate (Boc) group provides protection for the nitrogen during multi-step syntheses, allowing selective deprotection under mild conditions. This compound is especially useful in medicinal chemistry for developing drug candidates within oncology and central nervous system disorders.
