Procedure

A mixture of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid (70 mg, 0.225 mmol), 2-methylbut-3-yn-2-amine (28 mg, 0.338 mmol), HATU (171 mg, 0.45 mmol) and DIEA (58 mg, 0.45 mmol) in DMF (3 mL) was stirred at room temperature for 16 hours. Then the mixture was poured into water and filtered to give the crude product. The crude compound was then washed with MeOH to give 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-N-(2-methylbut-3-yn-2-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (20 mg, 23.5%).
