Procedure
A mixture of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid (60 mg, 0.193 mmol), 2-amino-2-methylpropanenitrile (25 mg, 0.29 mmol), HATU (217 mg, 0.57 mmol) and DIEA (74 mg, 0.57 mmol) in DMF (3 mL) was stirred at room temperature for 16 hours. Then the mixture was filtered and the cake was washed with DMSO and MeOH to give N-(2-cyanopropan-2-yl)-2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (15 mg, 20.5%) as light yellow solid. MS: (M+H)+=400; 1H NMR (300 MHz, DMSO): δ 13.03 (s, 1H), 9.13 (s, 1H), 8.58 (s, 1H), 8.54-8.50 (m, 1H), 8.35 (s, 1H), 7.32-7.69 (m, 1H), 7.23-7.22 (m, 1H), 4.17 (s, 3H), 1.88 (s, 6H).
