Discovery of 3-Amino-4-Chlorophenyl P1 as a novel and potent benzamidine mimic via solid-phase synthesis of an isoxazoline library

In an effort to identify orally bioavailable factor Xa inhibitors, two isoxazolines libraries were prepared to scan for novel P1 ligands. From this work, 4-chloro-3-aniline was identified as a novel and potent benzamidine mimic.
