実験手順

A suspension of (S)-tert-butyl 3-(3-bromophenyl)-1-((4-methoxyphenyl)(methyl)amino)-1-oxopropan-2-ylcarbamate (6.3 g, 13.6 mmol), 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (3.3 g, 20.4 mmol), potassium carbonate (54 ml, 0.4 M) and tetrakis(triphenylphosphine)palladium(0) (0.79 g, 0.68 mmol) in 50 ml of DME, was heated at reflux overnight. The suspension was cooled and filtered through celite. The filtrate was washed with brine and filtered through celite. The organic layer was dried over Na2SO4, filtered and concentrated. The crude product was introduced to a silica gel loading column and purified by column chromatography (15-35% EtOAc/hexanes) to provide the desired product (5.47 g, 13.33 mmol), 94%. MS (m/z) 411 [M+H]+.
