Versuchsvorschrift

A mixture of 2-(6-chloro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (0.07 g, 0.3 mmol), 2-methylbutan-2-amine (0.05 g, 0.57 mmol), EDCI (0.057 g, 0.3 mmol), DMAP (0.037 g, 0.3 mmol), HATU (0.114 g, 0.3 mmol) and DIPEA (0.163 g, 1.26 mmol) in 10 mL of DMF were stirred at room temperature overnight. The solvent was removed under reduced pressure at 70° C. The residue was triturated with water and then purified by preparative-HPLC (Gemini 5u C18 150×21.2 mm; inject volume: 3 mL/inj, flow rate: 20 mL/min; wavelength: 214 nm and 254 nm; the gradient conditions were: 57% acetonitrile/43% water (0.1% trifluoroacetic acid, v/v) initially, proceeding to 80% acetonitrile/20% water (0.1% trifluoroacetic acid, v/v) in a linear fashion over 9 min.) to give 2-(6-chloro-1-methyl-1H-indazol-3-yl)-N-tert-pentyl-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (0.019 g, 22%) as a white solid. MS: (M+H)+=397; 1H NMR (300 MHz, DMSO): δ12.86 (s, 1H), 9.10 (s, 1H), 8.47-8.40 (m, 2H), 8.03 (s, 1H), 7.83 (s, 1H), 7.32 (d, 1H, J=8.4 Hz), 4.20 (s, 3H), 2.03-1.91 (m, 2H), 1.48 (s, 6H), 0.89 (t, 3H, J=7.4 Hz).
