実験手順

To a solution of tert-butyl [2-(4-bromophenyl)ethyl]-[(2R)-2-hydroxy-2-(3-pyridyl)ethyl]carbamate (331 mg) in 1,4-dioxane (3.3 ml) were added [4-[[[(3-hydroxypropyl)sulfonyl]amino]carbonyl]-3-isopropoxyphenyl]boronic acid (325 mg), tetrakis(triphenylphosphine)palladium (91 mg) and aqueous solution of sodium carbonate (2M, 1.4 ml), and the mixture was stirred at 80° C. for 3 hours under nitrogen. The mixture was portioned into a mixture of ethyl acetate and water. The organic layer was separated, washed with brine, dried over sodium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (ethyl acetate/methanol=100/3) to give tert-butyl [2-[4′-[[[(3-hydroxypropyl)sulfonyl]amino]carbonyl]-3′-isopropoxy-4-biphenylyl]-ethyl][(2R)-2-hydroxy-2-(3-pyridyl)ethyl]carbamate (108 mg).
