Conditions

Temperature: 160 °C

Procedure

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). Methylamine (2M in THF, 0.129 ml, 0.26 mmol) and DIPEA (0.113 ml) were added and the mixture was heated at 160° C. for 4 h under microwave irradiation. Further methylamine (2M in THF, 0.129 ml, 0.26 mmol) was added and the mixture was again heated at 160° C. for 1 h under microwave irradiation. The crude reaction mixture was dissolved in DMSO/MeOH (1:1) and purified by Mass Directed Automated Preparative HPLC (Method B). Product-containing fractions were dried under a stream of nitrogen to afford the title compound (4.4 mg) as a pale yellow gum.
