Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents such as antipsychotics and antidepressants. Its stereochemistry allows for selective interaction with biological targets, enhancing drug efficacy and reducing side effects. Commonly employed in the preparation of neurokinin receptor antagonists and other CNS-active compounds. The presence of both amine and methoxy functional groups enables diverse chemical modifications, making it valuable in medicinal chemistry for building complex drug molecules.
