Reaction Steps

The compound (R)-2-(6-(4-(1,3,4-oxadiazol-2-yl)phenylamino)-5-cyanopyrazin-2-ylamino)butanamide (57 mg, 0.156 mmol) was dissolved in EtOH (2 mL) and DMSO (1 mL), aq. 1N NaOH (1.0 mL) and aq. H2O2 (30%, 1.0 mL) were added. The mixture was stirred at room temperature for 30 min. HOAc (0.5 mL) was added. The mixture was then concentrated in vacuo. The residue was purified by HPLC to give the titled compound (3 mg). MS 383.3 (M+H); UV 204.7, 275.5, 329.8 nm; t 0.449 min.
