Procedure
A mixture of 5-chloro-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (503.0 mg, 0.91 mmoL), thiomorpholine 1,1-dioxide (367.1 mg, 2.72 mmoL), NaHCO3 (533.0 mg, 6.34 mmoL) in NMP (8 mL) was heated at 130° C. overnight. The mixture was cooled to room temperature and diluted with H2O and then extracted with ethyl acetate (×2). The combined organic layers were washed with brine and dried with Na2SO4. Evaporation of solvent afforded the crude displacement compound. Purification by column chromatography afforded compound 5-thiomorpholinodioxo-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine LCMS tR=2.52 Min (5 min run, UV254nm). Mass calculated for, M+ 654.2, observed m/z 655.2 (M+H).
