Participants

Reaction Steps

To a solution of 4-((1R,2S)-2-aminocyclohexylamino)-5-fluoro-2-(3-phenylisoxazol-5-ylamino)benzonitrile in EtOH (1 mL) and DMSO (0.5 mL), 1N aq. NaOH (0.5 mL) and H2O2 (50% aq., 0.5 mL) were added. After being stirred at room temperature for 1 h, the mixture was concentrated in vacuo. The residue was acidified with HOAc (0.5 mL), and then was purified by HPLC to give the titled compound (33 mg). MS 410.3 (M+H); UV 204.7, 246.1, 287.8 nm.
