Versuchsvorschrift

N-Iodosuccinimide (1.26 g, 5.61 mmol, dissolved in 25 ml acetonitrile) was added into a solution of di-tert-butyl 5-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)pyrazolo[1,5-a]pyrimidin-5-yl)piperidine-1,2-dicarboxylate (3.8 g, 5.61 mmol) in acetonitrile (26 mL). The reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was concentrated in vacuo and purified via silica gel chromatography (0% to 30% ethyl acetate in hexanes gradient) to yield the title compound (3.16 g, 70% yield) at clear oil. LC-MS: 804 [M+H].
