N-Iodosuccinimide (811 mg, 3.6 mmol) was added into a solution of 4-{7-[bis-(2-trimethylsilanyl-ethoxymethyl)-amino]-pyrazolo[1,5-a]pyrimidin-5-yl}-cyclohexanecarboxylic acid methyl ester (Int-7e, 1.75 g, 3.27 mmol) in acetonitrile (25 mL). The resulting 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 (1.79 g, 82.8% yield) at clear oil. LC-MS: 703 [M+H].
