Procedure
6-fluoro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinoline (3.65 mmol, 996.4 mg), K3PO4 (9.12 mmol, 1933.6 mg), and PdCl2(dppf).CH2Cl2 (0.30 mmol, 248 mg) was added to a solution of 5-chloro-3-iodo-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (3.04 mmol, 1684.3 mg) in dioxane (18 mL) and H2O (3 mL). The resulting solution was stirred at 80° C. under argon overnight. The mixture was diluted with H2O and then extracted with ethyl acetate (×2). The combined organic layers were washed with brine and dried with Na2SO4. Evaporation and purification by column chromatography afforded 5-chloro-3-(6-fluoroquinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine: LCMS tR=3.34 Min (5 min run, UV254nm). Mass calculated for, M+ 573.2, observed LC/MS m/z 574.2 (M+H).
