Reaktionsschritte
A mixture of 2-bromo-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (0.2 g, 0.83 mmol), cyclohexane-1,3-diamine (0.473 g, 4.15 mmol), HATU (0.475 g, 1.25 mmol), DIPEA (0.322 g, 2.5 mmol) in 15 mL of DMF were stirred at room temperature overnight. The solvent was removed under reduced pressure at 70° C. to give N-(3-aminocyclohexyl)-2-bromo-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide as a crude which was used to the next step without further purification. MS: (M+H)+=338.1.
