실험 절차

A solution of (Z)-7-(2-ethoxyvinyl)-N-(3-methyl-1-((6-methylpyridin-2-yl)methyl)-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (82.8 mg, 0.177 mmol) in 1:1 dioxane/water (2 mL) was treated with 45 equivalents of 4.0 M hydrochloric acid in dioxane solution at ambient temperature. The reaction mixture was stirred at ambient temperature for 1.5 hours, quenched with saturated aqueous sodium bicarbonate solution, and extracted with DCM and EtOAc. The combined organic extracts were dried over anhydrous sodium sulfate, concentrated, and subjected to preparative thin-layer chromatography on silica with a 10% MeOH in DCM solution as eluent to afford 37 mg of the impure desired product as a yellow solid. The crude product was used in the next step without further purification.
