実験手順
EN04773-50, _Buchwald coupling,_ ** _J. Med. Chem. 2009, page 3846-3854 (changed: solvent to dioxane and bromide to iodide)._** The indole from 4773-41, 1-(benzyloxy)-3-iodobenzene, Pd2(dba)3, JohnPhos and KOtBu were dissolved in toluene. The mixture was warmed at 120 °C for 1h and ~40% conversion was observed on NMR. The reaction mixture was further heated at 80 °C for 16h and 40 h, see attached 1H-NMR for reaction progress. A comparison with 4773-51 shows that using dioxane or iodide gives a lower yield (slower reaction). Switching the solvent to toluene was explored in 4773-52. The reaction in this experiment showed that the Buchwald conditions worked. Reaction mixture was thrown away.
