3-Iodobenzyloxybenzene → 2-Methyl-1-(3-phenylmethoxyphenyl)-6-(trifluoromethoxy)indole

Temperatur

120 °C

EN04773-52, _Buchwald coupling, toluene and iodide_ The indole from 4773-25, 1-(benzyloxy)-3-iodobenzene,Pd2(dba)3, JohnPhos and KOtBu were dissolved in toluene. The mixture was warmed at 120 °C for 1h and 50% conversion was observed on NMR*(see attached NMR). The mixture was warmed further 15h at 120°C, still starting material left but the reaction mixture was directly applied to a silica column (heptane 3:1). Product was collected in fraction 22-23 (see attached NMR). Only 19.3 mg (10.45% yield) could be collected but NMR showed correct product. Test reaction with bromide was performed in 4773-53. ######################### *Small amount from reaction mixture was dissolved in CDCl3 and 1HNMR analysis was performed)
