Versuchsvorschrift

To a solution of 5-((1R,2S)-2-aminocyclohexylamino)-3-(isothiazolo[3,4-b]pyridin-3-ylamino)pyrazine-2-carbonitrile (36 mg) in EtOH (1 mL) and DMSO (0.5 mL), aq. 1N NaOH (1 mL) and aq. H2O2 (30%, 1 mL) were added. The mixture was stirred at room temperature for 20 h. After being neutralized with HOAc (0.3 mL), the mixture was purified by HPLC to give the titled compound (7 mg). MS found for C17H20N8OS as (M+H)+ MS 385.3. UV: λ=UV 207.4, 245.8, 298.6, 343.2 nm. 1H NMR: (CD3OD) δ 8.50 (dd, 1H), 8.22 (dd, 1H), 7.73 (s, 1H), 7.05 (dd, 1H), 4.70-4.62 (m, 1H), 4.12-4.05 (m, 1H), 2.14-1.60 (m, 8H).
