Reaction Steps
To a 10-20 mL microwave flask was added ethyl 2-(4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-iodopyrazolo[1,5-a]pyrimidin-5-yl)cyclohexyl)acetate (Int-5l, 1.41 g, 2.05 mmol), 6-chloropyridine-3-boronic acid pinacol ester (514 mg, 2.15 mmol), K3PO4 (1.31 g, 6.15 mmol), PdCl2(dppf).CH2O2 (167 mg, 0.21 mmol) and 9:1 1,4-dioxane:H2O (10 mL). The flask was flushed with argon and sealed. The reaction was stirred overnight at 100° C. After 18 hours, 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.
