Compound, 5-(4-(methylsulfonyl)phenoxy)-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (150 mg, 0.22 mmol) was dissolved in ACN (10 mL). NBS (40 mg, 0.22 mmol) was added and the mixture was stirred at room temperature for 1 h. After concentration, the residue, 6-bromo-5-(4-(methylsulfonyl)phenoxy)-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine was used in the next step without further purification. HPLC-MS tR=2.66 min (UV254 nm); mass calculated for formula C34H44BrN5O5SSi2 769.2, observed LCMS m/z 770.0 (M+H).
