실험 절차

A mixture of N-[5-(3,5-difluoro-benzenesulfonyl)-1-trityl-1H-indazol-3-yl]-4-(4-methyl-piperazin-1-yl)-2-[(tetrahydro-pyran-4-yl)-(2,2,2-trifluoro-acetyl)-amino]-benzamide (2.4 g, 2.53 mmol), 4N hydrochloric acid in 1,4-dioxane (35 mL), methanol (50 mL) and 1,4-dioxane (15 mL) was stirred at room temperature for 3 hours. The solvents were removed under reduced pressure and the residue dissolved in dichloromethane, washed with water, brine, dried over sodium sulfate and evaporated to dryness. The crude was purified by flash chromatography on silica gel using dichloromethane/acetone 1:1 as the eluant affording the title compound as a pale yellow solid (1.43 g, 80% yield).
