To a solution of 1-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-fluoroquinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)ethyl methanesulfonate (6.8 g, 10.3 mmol) in DMSO (100 mL) and N,N-diisopropyl-ethylamine (8.95 mL, 51.4 mmol) was added sodium azide (2.0 g, 30.8 mmol). After 4 hours the reaction was complete by HPLC. The contents of the flask were transferred to a separatory funnel, washed twice with water and twice with brine. The organics were dried over sodium sulfate, filtered and concentrated in vacuo to afford 5-(1-azidoethyl)-3-(6-fluoroquinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (6.2 g; 99% yield) as a dark yellow oil. HPLC: 6.67 min (Method D). LCMS: No ion detected.
