실험 절차

To a pressure tube flushed with N2 were added (S)-ethyl 2-(7-(4-(allyloxy)-4-methylpiperidin-1-yl)-2-(3-(2-bromophenyl)prop-1-en-1-yl)-5-methylpyrazolo[1,5-a]pyrimidin-6-yl)-2-(tert-butoxy)acetate (0.09 g, 0.141 mmol), acetonitrile (4 ml) and triethylamine (0.196 ml, 1.407 mmol). Added to this solution were triphenylphosphine (0.011 g, 0.042 mmol) and tris(dibenzylideneacetone)dipalladium (0) (0.013 g, 0.014 mmol). The tube was sealed and stirred at 120° C. After stirring for 20 h, the mixture was cooled, filtered and concentrated to give a yellow residue. The residue was purified by flash chromatography (Biotage; 0%-100% EtOAc/hexane; 20 CV) to give the title compound (0.0406 g, 0.073 mmol, 51.6% yield) as a sticky yellow oil. LCMS (M+H) calcd for C33H43N4O4: 559.32. found: 559.5.
