実験手順

Di-tert-butyl 5-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1,2-dicarboxylate (370 mg, 0.46 mmol) in methanol (12.6 mL) was treated with 4N hydrogen chloride in dioxane (5.4 ml). The reaction mixture was heated at 80° C. for 16 h, cooled to room temperature and concentrated in vacuo. The residue was purified by prep-LC to afford the title compound: LC/MS RT=2.31 min. Mass calculated for, M+H 403.18, observed 403.18.
