実験手順

A mixture of 6-bromo-9H-purine (0.262 g, 1.31 mmol), 1-[8-(4-{[tert-butyl(dimethyl)silyl]oxy}piperidin-1-yl)-5-chloroquinolin-7-yl]ethanamine (0.276 g, 0.657 mmol), and N,N-diisopropylethylamine (0.23 mL, 1.31 mmol) in ethanol (2 mL) was heated at reflux under nitrogen overnight. The mixture was evaporated and the resulting residue was diluted with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried and evaporated to dryness. The crude product was used directly in the next step (0.20 g, 57%). LCMS calculated for C27H37ClN7OSi (M+H)+: m/z=538.2; Found: 538.2.
