실험 절차

EN04773-53, _Buchwald coupling, toluene and bromide_ The indole from 4773-25, 1-(benzyloxy)-3-bromobenzene,Pd2(dba)3, JohnPhos and KOtBu were dissolved in toluene. The mixture was warmed at 100 °C for 2h. Ca 60% conversion according to LCMS (product at 2.31 min). This conversion rate seemed faster than for the corresponding aryliodide. Big bacth was performed in 4773-54.
