Reaction Steps
To a microwave vial was added 2 ml of a solution of 6-chloro-N-[6-(1H-indol-4-yl)-1H-indazol-4-yl]-2-pyridinecarboxamide (350 mg, 0.90 mmol, prepared as described in Example 18) in DMSO (14 ml). Diethylamine (0.027 ml, 0.26 mmol) and DIPEA (0.113 ml) were added and the mixture was heated at 160° C. for 2 h under microwave irradiation. Further diethylamine (0.027 ml, 0.26 mmol) was added and the mixture was heated at 160° C. for 2 h under microwave irradiation. Again, diethylamine (0.027 ml, 0.26 mmol) was added and the mixture was heated at 160° C. for 1 h under microwave irradiation. After this time, diethylamine (0.027 ml, 0.26 mmol) and DIPEA (0.113 ml) were both added to the mixture and it was heated at 160° C. for 2 h under microwave irradiation. The crude reaction mixture was dissolved in DMSO/MeOH (1:1) and purified by Mass Directed Automated Preparative HPLC (Method E). Product-containing fractions were dried under a stream of nitrogen to afford the title compound (4.7 mg).
