Conditions

Temperature: 160 °C

Procedure

To a microwave vial was added 2 ml of a solution of 6-chloro-3-fluoro-N-[6-(1H-indol-4-yl)-1H-indazol-4-yl]-2-pyridinecarboxamide (300 mg, 0.74 mmol) in DMSO (6 ml). Piperidine (0.024 ml, 0.25 mmol) and DIPEA (0.129 ml) were added and the mixture 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 further purified by Mass Directed Automated Preparative HPLC (Method E) and product-containing fractions were dried under a stream of nitrogen to afford the title compound (16 mg).
