実験手順

Potassium phosphate (498 mg), a 0.5M tetrahydrofuran-solution of B-benzyl-9-BBN (2.8 ml), palladium acetate(II) (21 mg), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (38.5 mg) were added to a solution of tert-butyl {[4-bromo-1-(3-methoxypropyl)-1H-indol-3-yl]methyl}cyclopropylcarbamate (205 mg) in N,N-dimethylformamide (4.3 ml) and the mixture was stirred under argon atmosphere at 80° C. for 3 hours. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine successively, dried over magnesium sulfate and concentrated in vacuo. The resulted residue was purified with a silica gel column chromatography (eluting solvent: n-hexane/ethyl acetate=20/1 to 2/1) to give tert-butyl {[4-benzyl-1-(3-methoxypropyl)-1H-indol-3-yl]methyl}cyclopropylcarbamate (210 mg) as a yellow oil.
