Reaction Steps

To a suspension of N-benzyl-N-tert-butoxycarbonyl-(3-trifluoromethoxy-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)amine (500 mg) in toluene (6 ml) and water (2 ml) were added phenylboronic acid (122 mg), sodium carbonate (210 mg) and tetrakis(triphenylphosphine)palladium(0) (35 mg), and the mixture was stirred at 80° C. for 3.5 hours. The resulting mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=30:1 to 20:1) to give N-benzyl-N-(3-phenyl-6,7,8,9-tetrahydro-5H-benzocyclohepten-6-yl)-tert-butoxycarbonylamine (494 mg).
