(3-Acetamidophenyl)boronic acid → (2R)-1-(3'-Acetamidobiphenyl-4-yloxy)-4-(3-pyridyl)-2-butanol

Participants

Reaction Steps

Prepared according to the method described in Example 33a) from (2R)-1-(4-bromophenoxy)-4-(3-pyridyl)-2-butanol (0.50 g), 3-acetamidobenzeneboronic acid (0.38 g) and tetrakis(triphenylphosphine)palladium(0) (0.045 g) in ethanol (1.7 ml), aqueous sodium carbonate solution (2 M, 1.55 ml) and toluene (6.9 ml) with heating at reflux for 1 hour. The residue obtained after work-up was purified by column chromatography over silica eluting with dichloromethane:methanol (92:8) to give the title compound (0.52 g) as an oil which crystallised from ethyl acetate and was recrystallised from isohexane/ethyl acetate.
