Procedure

To a solution of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanylethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [1-(cis-3-cyano-cyclobutyl)-ethyl]-amide (34 mg, 0.06 mmol) in CH2Cl2 (2 mL) was added TFA (1 mL, 13.0 mmol). The bright yellow-orange reaction mixture was stirred at room temperature for 3 h then concentrated. The residue was redissolved in CH2Cl2 (2 mL) and ethylene diamine (0.4 mL, 6.0 mmol) was added. The reaction mixture was stirred at room temperature for 1 h then concentrated directly purified via silica gel chromatography with 50% to 100% EtOAc/hexanes to 5% MeOH/EtOAc to afford 15 mg (58%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid [1-(cis-3-cyanocyclobutyl)-ethyl]-amide as a white solid. MS: (M+H)+=418; 1H NMR (DMSO-d6, 300 MHz): δ (ppm) 12.86 (br. s., 1H), 9.08 (s, 1H), 8.44 (s, 1H), 8.40 (dd, J=9.1, 5.3 Hz, 1H), 7.98 (d, J=8.7 Hz, 1H), 7.70 (dd, J=9.8, 1.9 Hz, 1H), 7.25 (td, J=9.0, 2.1 Hz, 1H), 4.17-4.28 (m, 1H), 4.14 (s, 3H), 3.20 (t, J=8.7 Hz, 1H), 2.30-2.46 (m, 3H), 2.04-2.20 (m, 2H), 1.18 (d, J=6.8 Hz, 3H).
