실험 절차

A flask equipped with a condenser was charged with the 7-chloro-N-(1-((6-isopropylpyridin-2-yl)methyl)-3-methyl-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (15.0 g, 32.68 mmol), (S)-2-(3,4-dimethylpiperazin-1-yl)ethanol (10.34 g, 65.37 mmol, Example 23), crushed KOH (9.17 g, 163.4 mmol) and 100 mL of DMSO. The mixture was heated to 95° C. for 22 hours. The mixture was allowed to cool to ambient temperature, 350 mL of water were added and the mixture stirred vigorously for 30 minutes. The mixture was extracted with EtOAc, and the combined organic extracts were washed with brine and 10% aqueous potassium carbonate, dried and concentrated. The resulting material was purified by column chromatography (10% MeOH/DCM/0.5% NH4OH to 15% MeOH/DCM/0.5% NH4OH) and then triturated with ether. The resulting solid was collected to give 10 g (53%) of the title compound. MS (APCI), positive scan, m/z=581.1 (M+H). [α]D=+5.6° (c=1.0, CHCl3).
