実験手順

As shown in Scheme 31 to a solution of 1-[4-(1-bromo-1-phenyl-methylene)-piperidin-1-yl]-2-(4,7-dimethoxy-6-azaindol-3-yl)-ethane-1,2-dione (0.094 g, 0.195 mmol), PdCl2(PhCN)2 (0.005 g, 0.0117 mmol), and CuI (0.005 g, 0.0252 mmol) in piperidine (1.5 mL) was added trimethylsilylacetylene (0.070 mL, 0.495 mmol). The mixture was heated at 60° C. for 2 h and the solvent removed in vacuo. The residue was diluted with EtOAc and H2O, the organic phase was separated and the aqueous phase was re-extracted with EtOAc (×2). The combined organic layers were washed, (H2O, brine), dried (Na2SO4) and evaporated, and the residue was purified by preparative HPLC to give the title compound as a colorless solid (0.038 g, 39%).
