実験手順
A solution of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (70 mg, 0.23 mmol), 1-methylcyclopropanamine (21 mg, 0.29 mmol), HATU (110 mmol, 0.29 mmol) and DIPEA (46 mg, 0.36 mmol) in 6 mL of DMF was stirred at room temperature for 16 hours. The solvent was evaporated at 70° C. under reduced pressure and the residue was triturated with dichloromethane (10 mL), methanol (10 mL) then decanted and dried to give 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-N-(1-methylcyclopropyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (45 mg, 54.9%) as a white solid. MS: (M+H)+=365; 1H NMR (300 MHz, DMSO): δ 9.09 (s, 1H), 8.54 (s, 1H), 8.48-8.42 (m, 2H), 7.71 (dd, 1H, J=9.9, 2.1 Hz), 7.25-7.24 (m, 1H), 4.16 (s, 3H), 1.49 (s, 3H), 0.81 (brs, 2H), 0.80 (brs, 2H).
