PROCEDURE
实验过程
3-iodo-5-(4-(methylthio)phenoxy)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (180 mg, 0.26 mmol) under Argon, was mixed with Pd(dppf)Cl2 (21 mg, 0.26 mmol, K3PO4 (106 mg, 0.5 mmol), 3-quinoline bornic acid (55 mg, 0.31 mmol) and dioxane (10 mL with 1 ml water). The resulting mixture was heated at 90° C. and stirred over night. After cooled to room temperature, the mixture was diluted with EtOAc (60 mL) and filtered through celite. After concentration, the crude was purified with column (silica gel, 0˜30% EtOAc/Hexane) gave the product 5-(4-(methylthio)phenoxy)-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (150 mg). HPLC-MS tR=2.85 min (UV254 nm); mass calculated for formula C34H45N5O3SSi2 659.3, observed LCMS m/z 660.1 (M+H).
