실험 절차

tert-Butyl 4-(5-{3-[3-({[(2,2,2-trifluoroethyl)amino]carbonyl}amino)phenyl]-imidazo[1,2-b]pyridazin-7-yl}pyridin-2-yl)piperazine-1-carboxylate (64 mg, 0.11 mmol) in methanol (0.5 mL) was treated with 4 N HCl in dioxane (0.4 mL) at r.t. for 1 h. The volatiles were removed under reduced pressure. The residue was dried in vacuum to afford the desired crude product which was used directly in next step without further purification. LCMS (M+H)+: m/z=497.1.
