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). Cyclopropylamine (0.018 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 cyclopropylamine (0.018 ml, 0.26 mmol) was added and the mixture was heated at 160° C. for 2 h under microwave irradiation. Again, cyclopropylamine (0.018 ml, 0.26 mmol) was added and the mixture was heated at 160° C. for 1 h under microwave irradiation. After this time, cyclopropylamine (0.018 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). The sample was re-purified by Mass Directed Automated Preparative HPLC (Method E, using Waters Atlantis column 100 mm×19 mm, 5 um). Product-containing fractions were dried under a stream of nitrogen to afford the title compound (1.9 mg).
