Procedure

The compound (R)-2-(5-cyano-6-(3-methylisothiazol-5-ylamino)pyrazin-2-ylamino)-3-cyclopropylpropanamide (143 mg, 0.323 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 15 min. HOAc (0.1 mL) was added. The mixture was then concentrated in vacuo. The residue was purified by HPLC to give the titled compound (39 mg). MS found for C15H19N7O2S as (M+H)+ MS 362.2; UV 205.4, 275.6, 324.4 nm; t 0.418 min. 1H NMR: (CD3OD) δ 7.51 (s, 1H), 6.69 (s, 1H), 4.68-4.60 (m, 1H), 2.28 (s, 3H), 1.84-1.75 (m, 1H), 1.65-1.57 (m, 1H), 0.82-0.72 (m, 1H), 0.40-0.28 (m, 2H), 0.10-0.0 (m, 2H).
