PROCEDURE

实验过程

NBS (246 mg, 1.38 mmoL) was added to a solution of tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yloxy)piperidine-1-carboxylate (Int-11b, 1022 mg, 1.38 mmoL) in CH3CN (15 mL). After stirring at room temperature for 30 min, the mixture was concentrated in vacuo. Purification by column chromatography afforded tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-6-bromo-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yloxy)piperidine-1-carboxylate (Int-11c): LCMS tR=3.59 Min (5 min run, UV254nm). Mass calculated for, M+824.3, observed m/z 825.1 (M+H).
