Procedure

A mixture of 5-chloro-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (77.9 mg, 0.14 mmoL), morpholine (36.7 mg, 0.42 mmoL), NaHCO3 (53 mg, 0.63 mmoL) in NMP (3 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 5-morpholino-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (70 mg, 82%). LCMS tR=2.72 Min (5 min run, UV254nm). Mass calculated for, M+ 606.3, observed LC/MS m/z 607.2 (M+H).
