Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment and targeted therapies. Its pyrimidine core with bromo and pyrrolidin-3-yloxy substituents enables selective binding to enzyme active sites and facile modification in medicinal chemistry. Commonly employed to modulate biological activity in drug candidates, including novel neuroprotective agents for neurological disorders like Alzheimer's, anti-inflammatory treatments, and CNS-acting compounds for conditions such as depression.
