実験手順

To 10-20 mL microwave flask was added ethyl 2-(4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-chloropyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate (Int-5m, 500 mg, 741 μmol), phenylboronic acid (181 mg, 1.48 mmol), K3PO4 (314 mg, 1.48 mmol), Pd(PPh3)4 (86 mg, 74 mol) and 3:1 1,4-dioxane:H2O (8 mL). The flask was flushed with argon and sealed. The reaction was stirred in a microwave at 150° C. for 30 minutes. After 30 minutes, the reaction was diluted with DCM and washed with H2O. The aqueous was extracted with DCM (x2) and the combined organic layers were dried over Na2SO4. The solvent was reduced in vacuo and the title compound was purified via silica gel chromatography.
