실험 절차

Under a nitrogen atmosphere, to toluene (1 mL) were added 5-bromo-2,2,4,6,7-pentamethyl-3-(4-methylphenyl)-2,3-dihydro-1-benzofuran (100 mg) and 3,4-dimethoxybenzylamine (56 mg), then palladium acetate (0.3 mg) and (S)-(−)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (2.7 mg), and further sodium tert-butoxide (37.5 mg). The mixture was stirred at 80° C. for 17 hours. Ethyl acetate was added to the reaction mixture, insoluble materials were filtered and the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, which was eluted with ethyl acetate-n-hexane [1:4], to obtain the title compound (80 mg, 64.5%).
