Versuchsvorschrift

2-[6-Fluoro-1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-3-yl]-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-methyl-2-pyridin-2-yl-ethyl)amide (75 mg, 0.117 mmol) was combined with dichloromethane (1 mL) then trifluoroacetic acid (0.26 ml, 3.50 mmol) was added. After stirring for 2 h, the reaction mixture was concentrated in vacuo. The residue was dissolved in dichloromethane (1 mL) and ethylenediamine (0.23 ml, 3.50 mmol) was added and the reaction was stirred at room temperature for 20 min. The reaction mixture was concentrated in vacuo and the residue was triturated with water (2 mL). The precipitate was filtered, washed with water and dried to afford 26 mg (41%) of 2-[6-fluoro-1-(2-pyrrolidin-1-yl-ethyl)-1H-indazol-3-yl]-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-methyl-2-pyridin-2-yl-ethyl)-amide (26 mg, 41%) as a yellow solid. MS: (M+H)+=513; 1H NMR (DMSO-d6) δ: 9.07 (s, 1H), 8.32-8.44 (m, 2H), 8.22 (d, J=8.3 Hz, 1H), 7.73 (d, J=9.8 Hz, 1H), 7.50-7.66 (m, 2H), 7.27 (d, J=7.8 Hz, 1H), 7.03-7.16 (m, 2H), 4.53-4.67 (m, 4H), 4.46 (s, 1H), 3.02-3.25 (m, 2H), 2.98 (t, J=6.5 Hz, 3H), 1.64 (br. s., 5H), 1.29 (d, J=6.5 Hz, 3H).
