A stirred mixture of (5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-3-{6-[2-{[(3-iodophenyl)methyl]oxy}ethoxy]hexyl}-1,3-oxazolidin-2-one (300 mg), 3-hydroxyphenylboronic acid (102 mg), tripotassium phosphate (417 mg) and dichlorobis(triphenylphosphine)palladium(II) (100 mg) in dimethoxymethane (10 ml) under nitrogen was heated under reflux for 4 h. The mixture was cooled to 20° and diluted with water (50 ml). The mixture was extracted with EtOAc (2×25 ml) and the combined extracts washed with water (50 ml) and dried (Na2SO4). Solvent evaporation in vacuo gave a residue which was purified by Biotage. Elution with diethyl ether gave the title compound (130 mg). LCMS RT=3.74 min, ES+ve 593 (MNH4)+.
