Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and anxiolytic drugs. Its structure allows for selective modifications, making it valuable in medicinal chemistry for creating analogs with improved bioavailability and receptor selectivity. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to introduce aryl or heteroaryl groups, enabling the construction of complex drug-like molecules. Also utilized in research settings for the development of novel benzoxazine derivatives with potential therapeutic activity.
