Versuchsvorschrift

A pressure tube was charged with 7-chloro-N-(1-((6-isopropylpyridin-2-yl)methyl)-3-methyl-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (0.500 g, 1.09 mmol), 2-((3R,5S)-3,4,5-trimethylpiperazin-1-yl)ethanol (0.375 g, 2.18 mmol), crushed potassium hydroxide (0.306 g, 5.45 mmol) in 10 mL of DMSO. The tube was sealed and heated to 95° C. for 16 hours, then allowed to cool to ambient temperature. The mixture was diluted with water and extracted with EtOAc. The combined organic extracts were washed with brine, dried over sodium sulfate, and concentrated under reduced pressure. Column chromatography (10% MeOH/DCM/0.5% NH4OH) followed by trituration with methyl t-butyl ether afforded 42 mgs (6%) of the title compound. MS (APCI), positive scan, m/z=595.1 (M+H).
