실험 절차

A mixture of 5-chloro-3-(6-fluoroquinolin-3-yl)-N,N-bis((2-(trimethylsilyl)ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (531.3 mg, 0.93 mmol), tert-butyl 4-aminopiperidine-1-carboxylate (556.6 mg, 2.78 mmol), NaHCO3 (467.2 mg, 5.56 mmol) in NMP (10 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 tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-fluoroquinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-ylamino)piperidine-1-carboxylate: LCMS tR=3.24 Min (5 min run, UV254nm), Mass calculated for M+737.4, observed m/z 738.3 (M+H).
