Procedure

2-[6-Chloro-1-(2-morpholin-4-yl-ethyl)-1H-indazol-3-yl]-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-pyridin-3-yl-ethyl)-amide (50 mg, 0.076 mmol) was combined with dichloromethane (1 mL) and trifluoroacetic acid (0.17 ml, 2.27 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 (0.15 ml, 2.27 mmol) was added. The reaction mixture was stirred for 20 min then concentrated in vacuo and the residue was triturated with water (2 mL). The precipitate was filtered, washed with water and dried to afford 29 mg (68%) of 2-[6-chloro-1-(2-morpholin-4-yl-ethyl)-1H-indazol-3-yl]-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-pyridin-3-yl-ethyl)-amide as a yellow solid. MS: (M+H)+=531; 1H NMR (DMSO-d6) δ: 9.11 (s, 1H), 8.71 (br. s., 1H), 8.43-8.58 (m, 3H), 8.29-8.38 (m, 1H), 8.05 (s, 1H), 7.86 (d, J=7.3 Hz, 1H), 7.36 (br. s., 1H), 7.15 (d, J=8.3 Hz, 1H), 5.35 (t, J=6.9 Hz, 1H), 4.65 (br. s., 2H), 3.50 (br. s., 4H), 3.33 (br. s., 4H), 2.84 (br. s., 2H), 1.68 (d, J=6.3 Hz, 3H).
