Versuchsvorschrift

To a solution of (S)-6-(5-cyclopropyl-1H-pyrazol-3-ylamino)-5-fluoro-2-(1-(4-fluorophenyl)ethylamino)nicotinonitrile (Example 1; 0.5 g, 1.3 mmol) in MeOH (50 ml), was added a 25% aqueous solution (2 ml) of KOH (400 mg) at 25° C., followed by the addition of 0.1 ml of 30% H2O2. The resulting dark red solution was heated to 65° C. for 1 h, cooled to 25° C., and concentrated. The resulting residue was dissolved in EtOAc (50 ml), washed with water (30 ml), dried, filtered and concentrated. The resulting solid was purified by column chromatography (DCM-MeOH=30:1) to give the title compound (0.30 g, 60%). 1H NMR (400 MHz, CDCl3) δ 9.06 (d, J=7.0 Hz, 1H), 7.90 (br s, 1H), 7.35-7.32 (m, 2H), 7.25 (d, J=7.2 Hz, 1H), 7.00-6.95 (m, 2H), 6.00 (br s, 1H), 5.66 (br s, 2H), 5.21-5.17 (m, 1H), 1.86-1.82 (m, 1H), 1.54 (d, J=6.8 Hz, 3H), 0.96-0.92 (m, 2H), 0.69-0.67 (m, 2H). MS: Calcd.: 398. Found: [M+H]+ 399.
