Versuchsvorschrift

Tetrakis(triphenylphosphine)palladium (40 mg) was added to a suspension of compound A (200 mg) and 5-(2-bromophenyl)-1-(4-nitrophenyl)-1H-tetrazole (202 mg) in toluene (2 ml) ethanol (0.5 ml) and 2M aqueous sodium carbonate (0.58 ml). The mixture was degassed and placed under an atmosphere of argon, then heated under reflux for 12 hours. The resulting solution was cooled to ambient temperature, and dichloromethane (30 ml) and water (10 ml) were added. The organic layer was separated, dried (MgSO4) and the solvent removed by evaporation. The residue was purified by flash chromatography, eluting with ethyl acetate/hexane (3:1 v/v), and the product triturated with ether/hexane to give 2-ethyl-4-[(2'-(1-(4-nitrophenyl)-1H-tetrazol-5-yl)biphenyl-4-yl)methoxy]-5,6,7,8-tetrahydroquinoline (134 mg) as a solid; NMR and m.p. similar to that obtained by procedure D.
