実験手順

A 50 mL roundbottom flask was charged ethyl 2-(4-(7-(bis((2-(trimethylsilyl)ethoxy)-methyl)amino)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate (381 mg, 0.68 mmol) and acetonitrile (10 mL). To this solution was added N-Iodosuccinimide (167 mg, 0.74 mmol). The reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was concentrated in vacuo and the crude oil was purified via silica gel chromatography (0% to 30% ethyl acetate in hexanes gradient) to yield ethyl 2-(4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-iodopyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate (335 mg, 0.49 mmol, 72% yield) as clear oil.
